Fractions
These codes allow fractions to be represented with typographically smaller numerators and denominators, but they can be replaced by other ways of typing a fraction (e.g. "1/2"). CSS Styling can also be used to achieve the same effect as described onGot Unicode and Lars Bruzelius.
Note: The code -- means no HTML entity code exists and that a numeric code must be used.

Some codes like that for x̄ (X-bar) are actually a combination of two codes - the base letter x plus a code for the line above (̄: or ̄). Note that a capital letter (e.g. the D in D-bar) may need to be reduced in size to accomodate the placement of the combining diacritic.
Note: These symbols use combining characters and may not appear correctly in older browsers such as Safari 2.

About The Codes
Use these codes if you need to insert a word or short phrase within a multilingual text.
Declare Unicode Encoding
The codes listed below are valid for Unicode HTML pages only, and may not work on very old browsers. To make your page a Unicode page, add the following meta tag to the<head> portion of your document.
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
...
<head>
If you forget to include this tag, then some browsers, such as Netscape 4.7, may not display the characters properly.
XHTML
The final close slash must be included after the final quote mark in the encoding header tag if you are using XHTML
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
...
<head>
No Encoding Declared
If no encoding is declared, then the browser uses the default setting, which in the U.S. is typically Latin-1. In that case many Unicode characters could be displayed incorrectly. Also, older browsers such as Netscape 4.7 may not be able to process the entity codes correctly without the "utf-8" declaration.
Using the Entity Codes
The Unicode numeric entity codes can be expressed as either decimal numbers or hexadecimal numbers.
For instance, the decimal version of the therefore symbol (∴) would be ∴
The hexadecimal version of the therefore symbol (∴) would be ∴
Note that the hexadecimal numbers include x as part of the code.
Windows Word Numeric Alt Codes
Use ALT plus the decimal version of any code to input it into a Windows document.
Note: These work only in Word 2003+ for Windows. Users with other software or versions of Windows may wish touse the Character Map instead.
