These special characters are shown in the table below they supplement the standard ASCII characters and ISO-8859-1 characters.

[edit] Explanations

The numbers used to represent these characters are actually the Unicode values. (See UTF-8) The page Named character references shows all of the Unicode characters by name as supported in HTML5.

In some cases the same glyph will appear for two different characters. It is still important to use the correct number code or word code since some processing programs such as MathML may be depending on it to properly format the data.

The Greek alphabet is only shown by samples. As can be seen from the samples it lies between #913 and #937 for upper case and from #945 to #969 for lower case. In Unicode this would be U-0391 to U-03A9 and U-03B1 to U-03C9. (These are hexadecimal digits.) PML supports the full Greek alphabet (and Hebrew).

The table shows the decimal values for numeric entries but hexadecimal values will work just as well. For example decimal character reference for the Euro symbol (€) is € and the hexadecimal character reference &#x20AC. The table also shows the character entity references called word code in the table. These are standard HTML entity references.

Notes Column:

The codes in the range of 300's in the table below are needed to augment ISO-8859-1 to support the pronunciation guide in a dictionary and the alphabet of some European countries. See also ISO-8859-15. The Word Code is the Entity reference if available.

[edit] footnotes

  1. If you do not have support for this character you could use <span style="font-size: 50%">&nbsp;</span> as a substitute.
  2. The &frasl; character allows you to create fractions that flow more proportionately with the surrounding text. 1/2 vs. 12 and 3/4 vs. 34
  • another method using small text: 12 or 34 [or with extra spacing & superscripts  2 or  4 ]
  • and another method using a mixture: 1/2 or 3/4 - using < sup > with the standard /
  • and another method using a mixture: 1/2 or 3/4 - using < small > and < sup > with standard /
  • and another method using a mixture: 12 or 34 - using < sup > with & frasl;

Note that the use of ligatures in text may cause searches to not find the character sequence. They can also cause problems when a document is converted if the new fonts in use does not contain the ligature.

[edit] Using special characters in Windows

You can use a character map to show and use all of the characters available in a particular font set that you have on your system. Select "Start » Programs » Accessories » System Tools » Character Map" to load the character map. You can then use copy and paste to select and use these symbols in your document.
