OpenSim has functions to generate dynamic textures, including text, but what fonts can it use?
For OpenSim on OS X (Server) it turns out that all fonts installed in /Library/System/Fonts in addition to fonts installed in ~/Library/Fonts for the user that OpenSim is running under is available to mono and therefore to OpenSim.
A discussion on how to make fonts available for OpenSim running on Linux and Windows can be found in the Kitely Blog, where they also provide a script for testing the fonts available.
A modified script that includes some of the Apple installed fonts is below. Place the script in a prim and scale it so the texture with the fonts becomes readable. Fonts existing on the system will show properly formatted, the rest will be set in the same type.
