Pretty much what the title says, works fine in a plain (non-X) Cygwin window. It's probably a charset thing. In case it's related:
$ echo $LANG C.UTF-8
I ungzipped the man page for less and the start looks like so:
.TH LESS 1 "Version 429: 11 Apr 2009" .SH NAME less \- opposite of more
Any ideas on how to fix this?
