The following Character Set table contains four columns:
Char. This is the actual character.
Code. This is the decimal code number for the character.
Name. This is the entity name for the character.
Description. A short description on the character.
In all cases, you may use the decimal code number to represent the character, or the entity name if that's available. A number is used like this:
µ to represent the 181th character. Since this character
also has a name, you can also use µ to represent it. This only works in HTML.
