I ain't say anything about UScript, I said about resources, folders/files involved.
Proof ? Did you read my post ? I formatted partition years ago - right after his "death". I unpacked those resources with funky names, and later I was surprised that I could not move those folders/files, the rest of data on disk had no problems. I'm not sure if I have that original archive somewhere and even if I would find it I won't unpack anything again.
For your knowledge, I witnessed such errors on Machines having USA as ONLY code page and some documents were copied from elsewhere - Some errors have been returned by Scandisk, yeah

exactly

. And No, I'm not crazy I recall well some of lousy PC things which I witnessed.
I you want another similar craps like that, look for some Android apps using stupid names (coming from other planet maybe), copy them from phone to PC and back and do some file handling tasks - you might have some entertaining occurrences... I was about to lose my backups and since that moment I'm renaming all TRASH used as app names in common names out of "characters" and I did not see any issue anymore. And yes, Android as a brother of Linux also might do
damage at this point into Win Systems - already happened. You might want to see a custom Romanian file name in Android translated into a Win machine how does it looks like - with a sort of alias code page installed as well - some Eastern Europe. When a file is saved from elsewhere into machine without that code page or another sort of naming deal, you can expect troubles if you want to move/delete that file. When you'll see such things don't say I did not warn you. If German specific stuff is well aligned between various platforms this doesn't mean that it's the same for everyone and for all countries. Already a lot of applications had patches for fixing various language issues, because YES, there are issues here.
And Yes, I'm polite and No, I'm not bullshitting.
