This was discussed here before but I'm not sure whether a solution was 
already outlined.
The problem appeared on Linux too, some years ago, but has been fixed 
meanwhile.
Differences are:
man calls nroff -mandoc on cygwin, nroff -mandocdb on Linux. The latter 
macro package of groff includes the following which is prepended to the 
manual page before feeding it to nroff for formatting:
.if '\*[.T]'utf8' \{\
.  char \- \N'45'
.  char  - \N'45'
.  char  ' \N'39'
.  char  ` \N'96'
.\}

Checking the program chain of 'man' with procps, some other macros are 
added already (simply using 'echo'), that's where it could also be added 
without a complete new macro package (i.e. without changing groff). 
However, the auxiliary roff codes are apparently hard-coded in man.exe 
so that'll have to be changed.
