Broken map configs

[grenadier]

Many custom map configs are broken, because they contain non-ASCII characters on the end of the file. Does anybody maybe know, why it happens, in what moment? It looks, that these broken configs were edited on Windows (CRLF chars), but why do there appear non-ASCII chars, why is it so common?

It happens during the save, I think someone explained me how to reproduce this but I don't remember.
