The following Character Set table contains four columns:

  1. Char. This is the actual character.
  2. Code. This is the decimal code number for the character.
  3. Name. This is the entity name for the character.
  4. 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.
