LuaGameScript.auto_save - valid chars?

RE: LuaGameScript.auto_save

Is there definitive info anywhere on which characters are/not permitted for the filename?

My random spot use of unicode chars suggests that if the factorio fonts support it, so does auto_save - with some (presumably file system driven) exceptions. It's these exceptions I'm particularly interested in.

Cheers.

The only limits on the name are what the underlying file system on your operating system imposes. The GUI imposes a bunch of restrictions because someone wanted to impose those restrictions - not because there's any code which can't deal with what the operating system supports.
