I'm working on a companion mod (yes, another of those pesky things...) and I have a question regarding the use of special characters in topics. For instance, the Special Slave Companions mod has the following topics set up like this:

-combat
-entertainment
-information

and so forth. This is really how I would like to set up my command and info topics for the companion, so they are all nicely sorted out. I don't want to use the dash though, because I don't want confusion with Special Slave topics if someone uses both mods.

My question is, are there characters that can't be used, and if so, what characters can be used?
