Trying to compress a file with "≠" in it's filename causes an error

For TAR and LZIP it seems to work fine... but with other formats it seems to either just show an error "Fatal error" and not compress a file with "≠" in it's filename, or it compresses it and shows an error "Minor error, the operation may have been completed".

Not that I need to use "≠" in filenames... but while I was trying to compress some files (a group of various files), there was some file among those files that had that character in it's filename for some reason (I guess that someone probably had a Cyrillic filename on some old version of Windows and that the encoding wasn't UTF-8 and that the encoding was messed up as it was transfers to newer operating systems)... and after trying to determine what was causing an error, it turned out that it was because of that file.

So, not very important... I just renamed that file to solve the issue... but I just thought that you would like to know about it.
