This web page is a human readable version of the DTD that can be found at http://www.w3.org/TR/xhtml1/DTD/xhtml-special.ent. This DTD specifies the available character entity for the Special set.
Typical invocation (for xhtml1) is by explicitly using the following tag in your document:
<!ENTITY % HTMLlat1 PUBLIC "-//W3C//ENTITIES Latin 1 for XHTML//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml-symbol.ent">
Usage
The table below gives the entity name, and the numeric code for the character. If you for example want to put a greek delta (δ) in your text, you can use either:
Here is a delta δ in my text
Or you can use:
