Below is the sample HTML I have written to understand about meta charset tag.
<!DOCTYPE html>
<html lang="en">
<HEAD>
<meta charset="ANSI" />
</head>
<body>
如
</body>
</html>
The BODY tag of this HTML contains chinese character.
Because chareset is set to "ANSI" , I was expecting that the chinese character will not be displayed in the browser, instead some junk character will get displayed.
I would like to know why chinese character is getting displayed correctly, even though charset is "ANSI" instead of UTF-8.
"ANSI" is not a valid value for charset.
A browser may also ignore the <meta> tag if:
the HTTP Content-Type header tells it otherwise;
there is a BOM at the beginning of the HTML; or
the browser does not think the page is in the named charset (see this process for determining a page's character encoding).

How do I get HTML to display ščž and other various special characters like ł,ß,ö..?
You need to specify a character set so the browser knows what's being used in the page. For example, in your head section, try putting:-
<meta charset="UTF-8">
You can also try specifying symbols using their entity name/code, using the character reference table here - https://dev.w3.org/html5/html-author/charref
Here's an HTML5 example. meta declares the encoding of the HTML file. Make sure to save the file in that encoding!
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Example</title>
</head>
<body>How do I get HTML to display ščž and other various special characters like ł,ß,ö,马..?</body>
</html>
You can enter any character you know the Unicode codepoint using &#xnnnn syntax. In the example above, U+9A6C is the Chinese character for horse(马).
I am using placerholder="" like this to show the users which word they have to translate: <input id="ha_1" placeholder="안녕하세요" type="text"> The Korean word 안녕하세요 displays perfectly in chrome, but gets messed up by Firefox and Edge (both newest version). It looks like this:
Any way to fix this directly or is there a workaround for that?
You have to define Character Encoding type inside of your html code.
What is Character Encoding?
ASCII was the first character encoding
standard (also called character set). ASCII defined 127 different
alphanumeric characters that could be used on the internet: numbers
(0-9), English letters (A-Z), and some special characters like ! $ + -
( ) # < > .
ANSI (Windows-1252) was the original Windows character set, with
support for 256 different character codes.
ISO-8859-1 was the default character set for HTML 4. This character
set also supported 256 different character codes.
Because ANSI and ISO-8859-1 were so limited, the default character
encoding was changed to UTF-8 in HTML5.
UTF-8 (Unicode) covers almost all of the characters and symbols in the
world.
for more information refer here.
Please use as following meta tag inside of your <head> tag.
<meta charset="UTF-8">
complete example.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Character Encoding</title>
</head>
<body>
<h1>안녕하세요</h1>
<input id="ha_1" placeholder="안녕하세요" type="text">
</body>
</html>
I have an HTML file that contains charset=utf-8 Unicode characters. I can read and show the content in a QTextBrowser. But the Unicode characters are not showing up properly. I think they are showing up using ANSI code equivalence which is very strange and unreadable.
How can I show the Unicode characters in a QTextBrowser?
You should set a meta tag in your HTML file to specify that the contents are in UTF-8 format. Put the tag in header :
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
...
</head>
QTextBrowser would show the unicode characters properly.
One way to specify the encoding of an HTML document is by sending the appropriate headers. However, a fallback approach is to declare the encoding inline via a meta tag. For example:
<!DOCTYPE html>
<html>
<head>
<title>Foo bar</title>
<meta charset="utf-8" />
</head>
<body>
<p>Hello, world!</p>
</body>
</html>
But to read the document and determine the encoding, must one not already know the encoding?
As long as no non-ASCII characters appear before that <meta> tag, the browser can assume that it's ASCII or UTF8, and it will read correctly until that point.
This is why that <meta> tag should be before the <title>.
If it's UTF16, the browser can figure that out by trying to read characters like <.
What is the correct way of declaring a HTML5 page to be in Hebrew, RTL and utf-8 encoded? I haven't done it in a while, but I remember that in HTML4 it involved 3 or 4 tags and attributes that seemed redundant. Is it still the same?
<html dir="rtl" lang="he">
<head>
<meta charset="utf-8">
...
</head>
...
</html>
You need the following:
A <!doctype html> to indicate your page is HTML5.
An <HTML> tag with the following attributes:
dir="rtl"
lang="he"
Note: you may omit the ", or use ' instead.
A <meta> tag to declare the character encoding. You can choose one of the following:
<meta charset="UTF-8">
Note: you may omit the ", or use ' instead.
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
This is the "legacy" way of declaring character encoding. It's still allowed within HTML5, but all modern browsers support the first variant so there is no need for this.
Note: you may omit the " for the http-equiv attribute, or use ' instead for all attributes.
If the browser encounters an UTF-8 byte order mark, it will treat an HTML5 file as UTF-8. This happens regardless of any character encoding declared using meta tags.
None of the tags, attributes and attribute values used here, or the DOCTYPE, are case sensitive.
Note: if the browser encounters a character encoding declaration, it will re-parse the document from the start using the specified encoding. You can put your encoding inside a Content-Type HTTP header so this won't be a problem.
Note also that the browser will only look for a character encoding declaration in the first 1024 bytes of a document.
You need these to create a HTML5 page with language as hebrew, direction as RTL, and utf-8 encoded
<!DOCTYPE html> For declaring it as a HTML5 page
<html dir="rtl" lang="he"> For direction and language
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> For utf-8
<html dir="rtl" lang="he">
not: <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
Does not work on "Chrome" and "Firefox" browsers.
