files with ë or é etc do not make it into playlist

[MiniMe]

Thanks for this directions. I'm on MacOs. Spent couple of hours trying to fix this, load it from text file to m3u/m3u8, convert txt to m3u8, load it into Excel Mac, copy paste manually but I'm still where I started. All players skip filenames with strange/unicode characters when I try to open them via a playlist. Even Mac Music app will skip the filenames with strange characters when it plays a m3u8 playlist. I may have invalid/unicode characters in my file names, but a quick Google search shows I'm not alone.
The only robust way would be manually replacing all these unicode char for normal a-z ascii. Or simply live with the fact I'm missing a few files of the whole when a playlist is used.
