Musescore not supporting file names of other languages

If i have the file named in another language, it uploads fine, but when I try to download it off the website, it'll only give me a file named "mscz". I can rename the file to "something.mscz" and it'll open fine though. Another thing is musescore also doesn't support opening files if the title is in a different language so if I named the file to like "你好.mcsz" it also wouldn't work
