Thought about it again. Probably was a stupid question.
Given that this is "my" game, I could say that this game supports filenames up 
to X characters and then use strncpy on the minimum of {real length, max 
length} everywhere.
I could adjust that maximum supported length to the needs of my current 
archives and would still have more room left than before when the game used 
Windows pathnames (because of the mounting).
Then only modders would have to be told to keep care on that length.
