you can use truetype-fonts or bitmap-fonts.
to create bitmap-fonts you can use Harry Potters font-creator (search in user constributions for this tool)
to get true type fonts you can download them. for example at
http://1000fonts.com (dont forget to ask for the permission of non-private use)
or you can create them too with the font creator (a commercial tool, get the trialversion here:
