If I generate a man page for this (pure comment) common.h:


  • \file common.h
  • \brief return -1

the generated common.h.3 contains

common.h -
return -1

The problem is that groff interprets plain '-' characters as hyphens, not minus signs, breaking search and copy&paste in the resulting man pages in UTF-8 locales (where these are represented as different characters). As Doxygen does not distinguish hyphens and minus signs, it should play safe by emitting only the latter, ie. inserting backslashes like it does with the separator above.

Please see also and the links therein.
