Display unicode in html

HTML Unicode (UTF-8) Reference

The Unicode Consortium develops the Unicode Standard. Their goal is to replace the existing character sets with its standard Unicode Transformation Format (UTF).

The Unicode Standard has become a success and is implemented in HTML, XML, Java, JavaScript, E-mail, ASP, PHP, etc. The Unicode standard is also supported in many operating systems and all modern browsers.

The Unicode Consortium cooperates with the leading standards development organizations, like ISO, W3C, and ECMA.

The Unicode Character Sets

Unicode can be implemented by different character sets. The most commonly used encodings are UTF-8 and UTF-16:

Character-set	Description
UTF-8	A character in UTF8 can be from 1 to 4 bytes long. UTF-8 can represent any character in the Unicode standard. UTF-8 is backwards compatible with ASCII. UTF-8 is the preferred encoding for e-mail and web pages
UTF-16	16-bit Unicode Transformation Format is a variable-length character encoding for Unicode, capable of encoding the entire Unicode repertoire. UTF-16 is used in major operating systems and environments, like Microsoft Windows, Java and .NET.

Tip: The first 128 characters of Unicode (which correspond one-to-one with ASCII) are encoded using a single octet with the same binary value as ASCII, making valid ASCII text valid UTF-8-encoded Unicode as well.

HTML 4 supports UTF-8. HTML 5 supports both UTF-8 and UTF-16!

The HTML5 Standard: Unicode UTF-8

Because the character sets in ISO-8859 were limited in size, and not compatible in multilingual environments, the Unicode Consortium developed the Unicode Standard.

The Unicode Standard covers (almost) all the characters, punctuations, and symbols in the world.

Unicode enables processing, storage, and transport of text independent of platform and language.

The default character encoding in HTML-5 is UTF-8.

If an HTML5 web page uses a different character set than UTF-8, it should be specified in the tag like:

Example

The Difference Between Unicode and UTF-8

Unicode is a character set. UTF-8 is encoding.

Unicode is a list of characters with unique decimal numbers (code points). A = 65, B = 66, C = 67, .

This list of decimal numbers represent the string «hello»: 104 101 108 108 111

Encoding is how these numbers are translated into binary numbers to be stored in a computer:

UTF-8 encoding will store «hello» like this (binary): 01101000 01100101 01101100 01101100 01101111

Encoding translates numbers into binary. Character sets translates characters to numbers.

How do I display Unicode as text in HTML?

How do I display Unicode as text in HTML?

I can’t manage to find a way to do this.For example ∞ ( infinity symbol ) to display as text in a HTML document

You have first to check what is the Content-Type header your server returns? Is it Content-Type: text/html; charset=UTF-8 ? See Character_encodings_in_HTML If the server returns the charset, either fix it or use it, it overrides user provided encoding. (see HTML entities).

If your server does not provide charset, then add one in the document, as early as possible (should be in the first 1024 bytes entirely). Again, see Character_encodings_in_HTML. The following header should do:

or for XHTML (the first line):

And if you do not/can not use UTF-8 for your document, use HTML entities like C Travel suggests.

You write the character, e.g. “∞”, in your authoring program , save the file as UTF-8 with BOM, and make sure that the fonts that you have declared for the page, or the relevant piece of text, contain the characters(s) you have included. For more information, see my Guide to using special characters in HTML. If problems remain, please post the code you have tried and specify how it fails (and on which browsers).

You can use the &#; HTML element. For codes: http://unicode-table.com/en/

And you have to use UTF-8 encoding for the file save, and you have to put UTF-8 meta tag in the header too. (If you didn’t already have this.)

HTML Unicode Issue: How to display special characters

Currently, I have my webpage set to Unicode/UTF-8. When trying to display a special character (for example, em dash, double arrow, etc), it shows up as a question mark symbol. I cannot change these characters to the HTML entity equivalent. How can I circumvent this issue?

A question mark in a lozenge, �, indicates a character-level error: the data contains bytes that do no represent any character, according to the character encoding being applied. This typically happens when the document is declared as UTF-8 encoded but is really in iso-8859-1, windows-1252, or some similar encoding. Windows-1252 is a common default encoding used by various programs on Windows platforms. So you may need to open the file in your authoring program and re-save it as UTF-8 encoded.

If problems remain, please post the URL. Posting the code alone is not sufficient, since the character encoding is primarily specified in HTTP headers.

If you see a question mark in a small box, then it might be a font-level problem (lack of glyph in the fonts being used), but this would be very rare for common characters like the em dash. Different browsers have different ways of indicating character- or font-level problems.

Make sure your document is set to the correct character encoding in the actual code editor, as well as in the doctype. Both are necessary. I spent hours trying to tweak HTML when the only problem was that I needed to set the text setting in Coda.

See the following screenshot:

Make sure your characters are actually UTF-8 characters. They will probably look something like this:

Using Html/CSS, how to display overlapped/composed UNICODE characters (without using diacriticals marks)?

Currently, I search to display 2 characters equivalent to |< and >| where

On first message, I requested that vertical is represented by | = 0x2503 unicode character, but this character, in Arial, is not defined correctly on Chrome and on Edge Chromium.

When HTML code and style are following

div.std > span.char < font-family: Arial; font-size:80px; background-color: lightgreen; > On Chrome browser, I get following output

The 2 left characters must be composed so that | character is linked to left point of triangle.

The 2 right characters must be composed so that | character is linked to right point of triangle.

How can I do ?

This display is use to define 4 buttons to allow navigation in a list.

For this reason, it is important that

1. all buttons have same height
2. button |< and >| have same width
3. button < and >have same width
4. all characters are centered in green rectangle
5. alls gaps between 2 successive buttons have same width

It is also important that solution proposed works on any browser.

PS: centered means that left and right paddings are equal for all characters and top and bottom paddings are also equal for all characters.

For example in this question, 2 things are not correct.

1. in first and last bloc, bar and triangle characters are not linked together
2. left padding of first bloc is too large (not= right padding)
3. right padding of last bloc is too large (not= left padding)

Use a font that will always render the same and rely on letter-spacing to remove the unwanted space :

.uni < font-family: 'Inconsolata', monospace; >.uni span:first-child, .uni span:last-child

Or simply use CSS to build the shape and you can easily control everything:

In using only CSS, I have obtained following result

This can be done using following code

span.bar-triangle < display:inline-block; width: 1.82ch; >span.bar-triangle > span.bar < position:relative; padding-left:10px; background-color: transparent; >span.bar-triangle > span.triangle < background-color: transparent; position:relative; left: -0.40ch; >span.triangle-bar < display:inline-block; width: 1.82ch; >span.triangle-bar > span.triangle < padding-right:0.24ch; background-color: transparent; >span.triangle-bar > span.bar < position:relative; left: -0.60ch; background-color: transparent; >div < font-family: Arial; line-height:452%; font-size:20 >div > span.char

This code fix width of bar-triangle rectangle. Changing display to inline-block is necessary to fix the width.

This code move bar character to the right so that left space is more large. Parameter background-color is set to transparent because background’s color is set in bar-triangle rectangle.

span.bar-triangle > span.triangle

This code shifts triangle’s character to the left until left angle touch vertical bar.

As for bar-triangle , this code fixes width of triangle-bar rectangle.

span.triangle-bar > span.triangle

This code increment right padding to that left-paddind and right padding are equal and composed character continue to be centered in triangle-bar rectangle.

This code shifts vertical bar to the left so that right’s angle touches vertical bar.

This code set font’s family.
The line-height parameter is used to grow composed character rectangle height. The font-size parameter is used to fix gap between yellow rectangle.

This code set backgroung’s color of button’s rectangle and size of character displayed in rectangles.

If line-height parameter is not used, we obtain following result

There exists perhaps another solution to avoid to use line-height but I don’t find it.

Another possibility, is to replace by .

Displaying Unicode Symbols in Html

You should ensure the HTTP server headers are correct.

Content-Type: text/html; charset=utf-8

The meta tag is ignored by browsers if the HTTP header is present.

Also ensure that your file is actually encoded as UTF-8 before serving it, check/try the following:

• Ensure your editor save it as UTF-8.
• Ensure your FTP or any file transfer program does not mess with the file.
• Try with HTML encoded entities, like &#uuu; .
• To be really sure, hexdump the file and look as the character, for the ✔, it should be E2 9C 94 .

Note: If you use an unicode character for which your system can’t find a glyph (no font with that character), your browser should display a question mark or some block like symbol. But if you see multiple roman characters like you do, this denotes an encoding problem.

how to display unicode in html without javascript?

The codepoints website appears to have a solution. They use the Symbola font which is added to the page using @font-face , and that renders some unicode symbols correctly, including the one specified in your question.

@font-face include (for testing, don’t actually link to codepoints stylesheet when in production, instead copy it locally and link there instead):

Special character not displaying as expected

2 — Check if your HTML Editor’s encoding is in UTF8. Usually this option is found on the tabs on the top of the program, like in Notepad++.

3 — Check if your browser is compatible with your font, if you’re somehow importing a font. Or try and add a css to set your fonts to a default/generally accepted one like

body
 font-family: "Times New Roman", Times, serif;
