      I don’t know about dangerous, but case-insensitive Unicode comparison is annoying, expensive and probably prone to footguns compared to a simple byte-for-byte equality check.

      Obviously, it can be done, but I guess Linux devs don’t consider it worthwhile.

      (And yes, all modern filesystems support Unicode. Linux stores them as arbitrary bytes, Apple’s HFS uses… some special bullshit, and Windows uses UTF-16.)

        so if linux stores file names as arbitrary bytes them could I modify a ext4 fs to include a / in a file name

          If you did it would likely break something as it’s one of only two characters not allowed in a file name (the other being null).

          You can do a lot of funky stuff within the rules though, think about control characters, non-printing characters, newlines, homographs, emojis etc. and go forth and make your file system chaos!
