I'm loading data with an RSS feed into a Flex application.
Some of the data has html special characters. It can't read é,è,à,ç and other similar letters that are used in French for example. It gives a strange code instead of the letters with accents.
Now I use for reading HTML texts in Flex, but how can I remove these special characters?
Thanks!

use "restrict" property of the component so that it takes some specific type of string. Something like mentioned below
myTextBox.restrict = "A-Z a-z 0-9",
You can use RegExp for removing those French letters.

My problem occurs when I try to use some data/strings in a p-element.
I start of with data like this:
data: function() {
return {
reportText: {
text1: "This is some subject text",
text2: "This is the conclusion",
}
}
}
I use this data as follows in my (vue-)html:
<p> {{ reportText.text1 }} </p>
<p> {{ reportText.text2 }} </p>
In my browser, when I inspect my elements I get to see the following results:
<p>This is some subject text</p>
<p>This is the conclusion</p>
As you can see, there is suddenly a difference, one p element uses and the other , even though I started of with both strings only using . I know and technically represent the same thingm, but the problem with the string is that it gets treated as a string with 1 large word instead of multiple separate words. This screws up my layout and I can't solve this by using certain css properties (word-wrap etc.)
Other things I have tried:
Tried sanitizing the strings by using .replace( , ), but that doesn't do anything. I assume this is because it basically is the same, so there is nothing to really replace. Same reason why I have to use blockcode on stackoverflow to make the destinction between and .
Logged the data from vue to see if there is any noticeable difference, but I can't see any. If I log the data/reportText I again only see string with 's
So I have the following questions:
Why does this happen? I can't seem to find any logical explanation why it sometimes uses 's and sometimes uses 's, it seems random, but I am sure I am missing something.
Any other things I could try to follow the path my string takes, so I can see where the transformation from to happens?
Per the comments, the solution devised ended up being a simple unicode character replacement targeting the \u00A0 unicode code point (i.e. replacing unicode non-breaking spaces with ordinary spaces):
str.replace(/[\\u00A0]/g, ' ')
Explanation:
JavaScript typically allows the use of unicode characters in two ways: you can input the rendered character directly, or you can use a unicode code point (i.e. in the case of JavaScript, a hexadecimal code prefixed with \u like \u00A0). It has no concept of an HTML entity (i.e. a character sequence between a & and ; like ).
The inspector tool for some browsers, however, utilizes the HTML concept of the HTML entity and will often display unicode characters using their corresponding HTML entities where applicable. If you check the same source code in Chrome's inspector vs. Firefox's inspector (as of writing this answer, anyway), you will see that Chrome uses HTML entities while Firefox uses the rendered character result. While it's a handy feature to be able to see non-printable unicode characters in the inspector, Chrome's use of HTML entities is only a convenience feature, not a reflection of the actual contents of your source code.
With that in mind, we can infer that your source code contains unicode characters in their fully rendered form. Regardless of the form of your unicode character, the fix is identical: you need to target these unicode space characters explicitly and replace them with ordinary spaces.
.icon-a:before { content: '\e803'; }
.icon-b:before { content: '\e96f'; }
Okay I know content can be used to render URL or quotes but what is happening in the above code?
I came across this code and it is confusing, I tried googling I can't find any.
Any help would be appreciated.
Thanks.
Quoting papiro as suggested here
Put simply, they're Unicode references. The "\e601", for example, is the hex code 0xe601. If you go here: http://unicodelookup.com/#0xe601/1 you'll see that the entry for that character is totally blank. It's in a part of the Unicode character set reserved for "private" use. Meaning icon libraries and the like can place whatever they want in those spots and not have to worry about overriding common characters like those of any of the alphabets of the world or a Chinese character, for instance.
In your case \e803 reffers to unicode character this
Hope this helps
It depends on font you are corrently using in parent element. This code is Unicode character code, which can display �. After \ code of character is entered.

Regex to match only letters
(20 answers)
Closed 8 years ago.
I'm trying to create a regex for a HTML5 input so a user can only insert alpha characters that may be in a name. So characters from a-z, but also including ö,ü,â,æ ... and so on whilst also allowing whitespace and hyphens .
I have played around with some pattens but nothing seems to work correctly, this is what I have so far: <input type="text" name="firstname" pattern="[a-zA-Z\x7f-\xff] " title="">
Does anyone have a quick answer for this?
Since the HTML5 pattern attribute uses the same regex syntax as JavaScript, there is no simple way to refer to all alphabetic characters. You would need to write a rather huge expression (and to update it as new alphabetic characters are added to Unicode). You would need to start from the Unicode character database and the definition of General Category of characters there, or rely on someone having done that for you.
However, for your practical purposes, testing for “alpha characters that may be in a name” is even more complex. There are non-alphabetic characters used in names, such as left single quotation mark (‘) in addition to normal quotation mark (’), and who knows what characters there might be? If this is about people’s real names, it is very difficult to impose restrictions that do not discriminate. If this is about user names in a system, for example, you can define the repertoire as you like, but [a-zA-Z\x7f-\xff] does not look adequate (it includes some control characters and some non-alphabetic characters and excludes many Latin letters commonly used in Europe).
There is a very simple method to apply all you RegEx logic(that one can apply easily in English) for any Language using Unicode.
For matching a range of Unicode Characters like all Alphabets [A-Za-z] we can use
[\u0041-\u005A] where \u0041 is Hex-Code for A and \u005A is Hex Code for Z
'matchCAPS leTTer'.match(/[\u0041-\u005A]+/g)
//output ["CAPS", "TT"]
In the same way we can use other Unicode characters or their equivalent Hex-Code according to their Hexadecimal Order (eg: \u0100–\u017FF) provided by unicode.org
Try: [À-ž] as an example of Range. Modify your Range according to your requirement.
It will match all characters between À and ž.
Sample regEx would be
/[A-Za-zÀ-ž\-\s]+/

How would I escape space characters in a JSON string? Basically my problem is that I've gotten into a situation where the program that reads the string can use HTML tags for formatting, but I need to be able to use these HTML tags without adding more spaces to the string. so things like
<u>text</u>
is fine, for adding underline formatting
but something like
<font size="14">text</font>
is not fine, because the <font> tag with the size attribute adds an extra space to the string. I know, funny criteria, but at this point thats what has happened.
My first speculative solution would be to have some kind of \escape character that JSON can put in between font and size that will solve my "space" problems, something that the HTML will ignore but leave the human readable string in the code without actual spaces.
ex. <font\&size="14">text</font>
displays as: text
kind of like but better?
any solutions?
You can use \u0020 to escape the ' ' character in JSON.
I wanted to put a bar over my variable such as not(x) and also some set symbols in my web page? How do I incorporate that in my html page.
For the set symbols, you ought to use unicode HTML entities.
For the line over a variable (p), I'd rather use an alternate symbol for not, such as:
¬p (¬p)
You may also, as a commenter pointed out, use the combining diacritical unicode HTML entity like so:
p̅ (p̅)
Lastly, you may use one of the CSS methods provided.
<div style="text-decoration: overline">X</div>
