It may be because you're defining c in terms of itself, so you get a (non-terminating) recursive mapping. With another character it works: .tr k\[red-c]o\[slashed-o] bock It also works if you define "red-c" not in terms of "c", but the character encoding number: .char \[red-c] \m[red]\N'99'\m[] bock
