Should the filesystem also ban you from having files named both "thisfile" and "thisfilе" (Cyrillic lowercase ye)? In what character sets?

  IMHO yes. That kind of ambiguity can be a serious security risk.

    You said earlier that a distinct glyph looking identical to Latin I with its own lowercase is a problem, but you also say Cyrillic E should be folded into the Latin one? So should Turkish I with its own lowercase be folded into the normal Latin one or not? At any rate, I recognize you disagree with this, but there's something to be said for the filesystem to be a bag of bytes that doesn't care about any of this. Let higher-level, more user-facing pieces concern themselves with it. They're much more likely to know more about the end user's expectations than ext4.

  And also I, l and 1, which look the same in some fonts!
