I don't see where you're getting that either of us want the bytes to be collated. I don't even know what you mean by "collated", since collating is not what tr does, except when ordering ranges. > you just write the > literal \50102. Even if octal values could be more than three digits, I have no idea what you think 50102 is. Its decimal value is 20546. Its hex value is 0x5042. I have no idea what it has to do with character U+00F6 whose UTF-8 representation is 0xC3 0xB6..... I just realized what you're doing, 0xC3B6 has the _decimal_ value 50102, I have no idea why you would think _that_ is a representation people would want to use. If you're so pro-unicode, make it accept \u00F6 - that's a valid extension. But reusing the syntax POSIX uses for three-digit octal literals, for arbitrarily long decimal literals that aren't even unicode code points, makes no sense at all.

Because collating elements are the thing POSIX forbids which you appear to have _misinterpreted_ as forbidding multibyte characters. Otherwise I have _no idea_ what in POSIX you interpret as preventing reasonable behavior with UTF-8 multibyte characters. > I stated that I did not implement collating elements into this tr(1) at > the beginning and that it's a POSIX-nightmare to do so, bringing harm > to anybody who is interested in a consistent, usable tool. tl;dr: Collating elements = POSIX forbids them = You don't want them anyway. Multibyte characters = POSIX allows/requires them = You like them too. What is the problem? I don't know what you want to do that you think POSIX doesn't allow.
