Thanks for the scripts. As some background, I'll just note that the current encoding markers in the iso_8859* pages were added in response to this 2009 bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=519209 It seems a reasonable idea to convert everything to UTF-8, but I have some concerns/questions. 1. Is the encoding line: '\" t -*- coding: UTF-8 -*- really needed, or does modern groff just work this out? 2. I'm concerned about backward compatibility issues. As in: what if someone loads the man pages onto a system with old groff. Now, as far as I can work out, groff added input unicode support in v1.20, 2009 (http://lists.gnu.org/archive/html/groff/2009-01/msg00011.html). So, perhaps that's long enough ago that we don't need to worry too much about these issues.
