I don't think maintaining our own mappings is viable. It just won't work, there are too many characters in Unicode. It was quite obvious that the .tr request you presented was only meant to illustrate the basic idea, not to be an actual (sic :) implementation. Unless i lack skill in searching documentation in info and PDF format, neither groff nor Heirloom provide a facility to convert strings to all caps. Consequently, if we want to recommend sentence- or title-case section titles in the source code, introducing such a facility will be required first. I'm not completely sure yet, but it would probably have to be new macro rather than a new escape sequence. Probably a string modification macro akin to .substring and .chop, maybe to be named .allcaps stringname The more obvious names .toupper and .towupper are slightly misleading because in C, they only convert single characters, not entire strings. Besides, .toupper is not ideal because in C, it only operates on ASCII characters while we need a facility to operate on Unicode codepoints, and .towupper is not ideal because it sounds overly technical.
