I have done it before, but you will get (personalize Anya) errors

Post by **Conqueror** » Thu Jan 30, 2020 2:57 am

It depends on what you allow.
In my case I only allowed Numbers (0...9), spaces ( ) and - _

At that time I checked personalize, TCP/IP and the statistics screen, in all cases I had no problems.

Remember that you should not allow them to add rare symbols

You actually need to be a bit more careful about this, for instance you need to also follow the file name requirements of the underlying OS (as save files get saved to disk using the character name), you also need to be wary of the fact that some OS do certain things with various special chars (Windows for instance trims any leading spaces).
