Yup. I'm aware of that, which is why I did not propose it as an actual patch. It's just a proof of concept, and it does work, as far as it goes--which is not far enough for non-English languages or the rare occasions when English words avail themselves of diacritics.

And yes, there are man pages in french, and I > believe, in a lot of other languages. I'm aware. The biggest problem I know of is that the uppercasing transform of German sharp S "ß" goes to "SS". (A recent version of Unicode did introduce a capital sharp S but it might have only specialized uses; I'm not sure all Germans would find it acceptable.) A 1-to-2 character mapping of course is beyond the ability of .tr. As I think John Gardner said, what we really need is a roff request to expose the underlying C library's toupper() and tolower() functions. A good feature to precede this one into 1.22.5, perhaps? Regards, Branden [1] All of these can be spelled without diacritics, but it is also acceptable according to most style manuals I've seen to preserve them, especially when they help to disambiguate pronunciation. The magazine _New Yorker_ is somewhat notorious for clinging to the dieresis as a signifier that a vowel cluster should not be pronounced as a diphthong.
