Package: cmark Severity: normal Tags: upstream Version: 0.30.2-6+b2 Hi,
When generating manpages from markdown syntax, cmark uses "\f[C]" to indicate code (represented between backticks in the markdown source). (It likely uses this too for code blocks and blockquotes.) This is not valid roff: 'C' is not a groff font name. I believe the EX (Example begin) and EE (Example end) macros would be more suitable: "Example regions are useful for formatting code", see groff_man(7). Lots of more details are available from https://savannah.gnu.org/bugs/index.php?64594 'bug #64594: [troff] "warning: cannot select font 'C'"' . The problem can be reproduced by running: % echo "`foo`" >foo.md % cmark -t man foo.md >foo.1 % groff -t -e -mandoc -Tutf8 foo.1 >/dev/null troff:foo.1:2: warning: cannot select font 'C' % cat foo.1 .PP \f[C]foo\f[] I've seen the warning emitted with man-db 2.13.0-1 and groff 1.23.0-7 (man-db 2.11.2 and groff 1.22.4 do _not_ emit the warning). See also #1076648: "aephea: causes groff warning "cannot select font 'C'" when using \verbatim{ } or \tt{ }" . Thanks, Bye, Joost
