Unicode is an international standard for encoding characters from most of the world's languages into a single consistent format. CreationWiki saves text as Unicode. If text is displayed as a series of "unknown characters" (which may be boxes or question marks depending on your operating system and browser), it is a sign that your system does not have any font installed that supports those characters, or that the default font does not, depending on your browser. (On the other hand, if some text is being displayed as a series of (seemingly) random characters, it may be a sign that your browser is forcing usage of a different encoding, and thus interpreting the characters as different ones.) No font (currently) supports every single character in the Unicode standard.
- See CreationWiki:Useful symbol for symbols currently supported by the Creation Wiki.
A partial list of fonts with large character repertoires follows. Several of these are continually being updated as the Unicode standard grows and evolves, so you may want to occasionally get the latest version.
The following fonts do not have the very large coverage of the previous ones, but do support special ranges (e.g. math/music/science symbols, minority languages) that are often not covered in others.
