Thanks much for linking Text::CleanFragment & Text::Unidecode. First one seems to do everything that I would do for <Windows file systems that are not NTFS>. It would be perfect to replace my code if degradation of Unicode could be optionally skipped on file systems where Unicode is non-issue.

I wanted to use icu or similar (or, the second module) to preserve some information; due to lack of time (motivation, really) never looked into that. The second one may solve that issue for me. Sweet👍🏽

Oh, there is Unicode::ICU💡 So should create an another version that first tries Unicode::ICU; failing that, Text::Unidecode. (ugh no, no, do not want to go further down this rabbit hole for cannot help but think of Tom C's response on Stack Overflow (on WayBack Machine aka web.archive.org))
