I want to put an email address on a website, and protect it (at least a little, I don't want to use JavaScript encoding) from spam.
The method I use is printing Unicode characters in my HTML, so bots don't recognise the email addresses.
The code:
somethingk@hotmailˬom
Output:
something#hotmailˬom
What goes wrong: The dot (002E) displays as a 02EC Unicode character. When I print . without any text directly next to it, the dot is displayed like it should.
Add a semicolon after HTML entities.
somethingk#hotmail.com

When I copy some text from an MS Outlook email and paste it into a contenteditable element (in Chrome), the clipboardData property of the paste event contains HTML that ends with some weird characters. It looks like this:
<html>
<head>...</head>
<body>
...
<!--StartFragment-->
...
<!--EndFragment-->
...
</body>
</html>
orati�o<�z�
The characters at the end are different each time, but they are always present.
I was wondering why these characters are there. Do they have any special meaning?
(Note that this does not seem to be an encoding issue: everything between the <html> tags looks valid and does not contain strange characters.)
It is likely that the Outlook email is encoded using a different character set to the editor you are pasting into; e.g. If the email is UTF-8 encoded and you paste into an ISO-8859 document then these replacement characters appear to represent those not recognized by ISO-8859.
As clearlight says, with the chars being at the end, this could be just buffer garbage. Try right-clicking the email and viewing source to determine if the html is well formed. Alternatively try forwarding the email to another address and viewing the source in another email client. This will confirm if its outlook or not.
You should simply ignore them, they don't have to do anything with the HTML code.

I noticed on my website, http://www.cscc.org.sg/, there's this odd symbol that shows up.
It says L SEP. In the HTML Code, it display the same thing.
Can someone shows me how to remove them?
That character is U+2028 or HTML entity code
which is a kind of newline character. It's not actually supposed to be displayed. I'm guessing that either your server side scripts failed to translate it into a new line or you are using a font that displays it.
But, since we know the HTML and UNICODE vales for the character, we can add a few lines of jQuery that should get rid of the character. Right now, I'm just replacing it with an empty space in the code below. Just add this:
$(document).ready(function() {
$("body").children().each(function() {
$(this).html($(this).html().replace(/
/g," "));
});
});
This should work, though please note that I have not tested this and may not work as none of my browsers will display the character.
But if it doesn't, you can always try pasting your text block onto http://www.nousphere.net/cleanspecial.php which will remove any special characters.
Some fonts render LS as L SEP. Such a glyph is designed for unformatted presentations of the character, such as when viewing the raw characters of a file in a binary editor. In a formatted presentation, actual line spacing should be displayed instead of the glyph.
The problem is that neither the web server nor web browser are interpreting the LS as a newline. The web server could detect the LS and replace it with <br>. Such a feature would fit well with a web server that dynamically generates HTML anyway, but would add overhead and complexity to a web server that serves file contents without modification.
If a LS makes its way to the web browser, the web browser doesn't interpret it as formatting. Page formatting is based only on HTML tags. For example, LF and CR just affect formatting of the HTML source code, not the web page's formatting (except in <pre> sections). The browser could in principle interpret LS and PS (paragraph separator) as <br> and <p>, but the HTML standard doesn't tell browsers to do that. (It seems to me like it would be a good addition.)
To replace the raw LS character with the line separation that the content creator likely intended, you'll need to replace the LS characters with HTML markup such as <br>.
This is the solution for the 'strange symbol' issue.
$(document).ready(function () {
$("body").children().each(function() {
document.body.innerHTML = document.body.innerHTML.replace(/\u2028/g, ' ');
});
})
The jquery/js solutions here work to remove the character, but it broke my Revolution Slider. I ended up doing a search replace for the character on the wp_posts tabel with Better Search Replace plugin: https://wordpress.org/plugins/better-search-replace/
When you copy paste the character from a page to the plugin box, it is invisible, but it does work. Before doing DB replaces, always have a database (or full) backup ready! And be sure to uncheck the bottom checkbox to not do a dry run with the plugin.
While Iam copying text phrase from notepad++ (phrase include spaces, copyright symbol (©), registered symbol (®) etc) to the html, after saving the html page, it is showing weird characters like  instead of space and other also.
On my html page, Iam having charset under meta tag like charset=UTF-8.
Issue is occurring while copying text from notepad++ only.
Please assist me to resolve this problem.
In HTML (as far as I know), you should always use HTML entities for representing characters like © (which is provided as ©). Here is a complete list of HTML Entities
I have got ឴symbol, that i can't display on web page (utf-8) content type. This symbol without width and can't see at all. How to show it? Code is ឴
for example here http://www.endmemo.com/unicode/khmer.php 6068 and 6069 are not visible, but i need to show it, at least space
Edited:
I'm using Arial or sans-serif. I think, that it is pretty usual fonts. What people do: they making UNIQUE text by inserting this symbol inside usual symbols. For example, user write: "a(invisible symbol of kmer)b(invisible symbol of kmer)" and so on. I see on page only "ab" without any spaces. I tried to put actual character inside html to see it, but with no luck. I thought that symbol, that is not present in font should be question mark or empty square, but not in that case. Solution can't just be simple replace in text.
If your page is UTF-8 then it's better to use the actual character rather than a HTML entity.
Your requested character is not present in many fonts. You can try finding the latest version of Code2000 which appears to support it.
You can see fonts that support this particular character here:
http://www.fileformat.info/info/unicode/char/17b4/fontsupport.htm
If you can't find a font and you want to display an empty space instead you could replace it before showing it in the page or put it in a container. The page you linked uses a table cell to hold the character.
This is driving me absolutely, !&&%&$ insane... it defies everything that I can think of.
THIS character right here... " "
In between these quotes... open google chrome and inspect. You will see its a ... normal right? Now right click and actually view the source of this stack overflow page. It's a regular space... (also, the character I copied was an actual space).
I could understand if it's some kind of rich text editor or something, but in the raw html source is a regular space, so what gives?
Here's just with hitting the space key (which works fine)... " ".
You can even copy it and paste it everywhere and wreak havoc and make chrome put everywhere. Even though whats copied in your clipboard is just a SPACE.
I have these stupid characters show up everywhere randomly in my website and I have no idea where they come from, or WHY is google converting a SPACE into a nbsp;
I have tried inspecting the actual character code and it's a regular space from all things I can find...
Every single method I try shows it as a NORMAL space... so what gives?
If i use ruby and do " ".ord I get 32. If i do it with the broken space I also get 32.
Please help me im losing my mind.
edit: you can prove this... view source on this page and you will see two empty " " like normal. Now look in console and only the one will be a , yet the raw source is identical.
Image for people not using chrome (this is looking at this very post via chrome dev tools):
Here's the HTML of the same text you see when you view source... no nbsp to be found.
When I view this page's source in Internet Explorer, or download it directly from the server and view it in a text editor, the first space character in question is formatted like this in the actual HTML:
THIS character right here... " "
Notice the entity. That is Unicode codepoint U+00A0 NO-BREAK SPACE. Chrome is just being nice and re-formatting it as when inspecting the HTML. But make no mistake, it is a real non-breaking space, not Unicode codepoint U+0020 SPACE like you are expecting. U+00A0 is visually displayed the same as U+0020, but they are semantically different characters.
The second space character in question is formatted like this in the actual HTML:
<p>Here's just with hitting the space key (which works fine)... <code>" "</code>.</p>
So it is Unicode codepoint U+0020 and not U+00A0. Viewing the raw hex data of this page confirms that:
It turns out the two seemingly identical whitespace characters are not the same character.
Behold:
var characters = ["a", "b", "c", "d", " "];
var typedSpace = " ";
var copiedSpace = " ";
alert("Typed: " + characters.indexOf(typedSpace)); // -1
alert("Copied: " + characters.indexOf(copiedSpace)); // 4
alert(typedSpace === copiedSpace); // false
JSFiddle
typedSpace.charCodeAt(0) returns 32, the classic space. Whereas copiedSpace.charCodeAt(0) returns 160, the   AKA character.
The difference between the two is that a whole bunch of repeated after one another will hold their ground and create additional space between them, whereas a whole bunch of repeated characters will squish together into one space.
For instance:
A B results in: A B
A B results in: A B
To convert the character with a character in a string, try this:
.replace(new RegExp(String.fromCharCode(160),"g")," ");
To the people in the future like myself that had to debug this from a high level all the way down to the character codes, I salute you.
Don't get yer knickers in a knot. It's one of those special html characters that we old-school love because we was tort rite.
For many of us, we were taught that a sentence started with a capital letter and ended with a full-stop. But the next sentence is separated from this by TWO spaces.
Good-ol'-HTML doesn't like space(s). If you enter a string of words with 5 spaces between them (using an unintelligent editor like MS Notepad, then html shows it with single spaces.
SO, to get it looking like we old-farts like, we end a sentence with '.&NbSp; Next' This puts two spaces after the full-stop, and looks like '. Next' rather than '. Next'.
Next point is that the real space (32) works as a linebreak, so that's good.
EXCEPT for we old-farts, who HATE to see our name split across a linebreak. That annoys us NO-END.
But, of course, that's where &NbSp; comes in handy again. If you enter 'John&NbSp;Brown', then the html thinks that's a single word, and it displays it just rite for we oldies.
How do these &NbSp; thingies get there? Well, good old Word (and I suspect many intelligent editors) see two spaces and output them as a non-breaking space followed by a normal space.
And when in Word, you can insert a non-breaking space between John and Brown by the key sequence alt-ctrl-space (sorry, you apple-users)
Lesson-over (with the exception that the term &NbSp; needs to be all lowercase - THIS viewer was even converting it)
It is a non breaking space. is the entity used to represent a non-breaking space. It is essentially a standard space, the primary difference being that a browser should not break (or wrap) a line of text at the point that this occupies.
Most likely the character is being inserted by your HTML Editor. Could you give a more specific example in context?
This is not actually an answer to the question but instead a tool that can be used to detect this special white space in the html of the pages of a website so we can proceed to locate and remove it.
The tool what basically does is:
Fetches the content of a URL
Looks for occurrences of chr(194).chr(160) in the HTML contents
Replaces and highlights the ocurrences with something more visible
This way you can actually know where the spaces are and edit your page properly to remove them.
The online version of the tool can be found here:
http://tools.heavydots.com/nbsp-space-char-detect/
A working example can be seen with the url of this question that contains one ocurrence:

There's a Github repo available if someone wants the code to run it locally:
https://github.com/HeavyDots/nbsp-space-char-detect
Hope someone finds it useful, for any feedback there's a comments section on the tool's page.

At our company blog we just wrote a funny post about this annoying white space. You're invited to drop by and read it! :-)
http://heavydots.com/blog/when-the-white-space-became-a-beast
As the previous answers have mentioned, it's a non-breaking space (nbsp). On Macs, this character gets inserted when you accidentally press Alt + Space (most of the time, this happens when entering code that requires Alt for special characters, e.g. [ on a German keyboard layout).
To remap this key combination to a plain ol' SPACE character, you can change your default keybinding as suggested on Apple SE
For whitespace, Press "Alt+0160" which is a character also.
