Hello,

Several manual pages contain non-ASCII characters; of course pages in
man7 describing encodings have to use non-ASCII characters, but pages
below contain non-ASCII characters only in groff comments:

 man2/close.2
 man2/getdomainname.2
 man2/getrlimit.2
 man2/madvise.2
 man2/sysinfo.2
 man2/umask.2
 man3/encrypt.3
 man3/fclose.3
 man3/fflush.3
 man3/lockf.3
 man3/rand.3
 man3/strtok.3
 man3/toupper.3
 man3/updwtmp.3
 man4/st.4
 man5/utmp.5
 man7/environ.7
 man7/hier.7
 man7/suffixes.7

The attached patch (compressed and not sent inline to avoid messing
with encoding) replace those characters by groff glyph names, as found
in groff_char(7).  This change is safe, since only comments are
modified.  In Fedora, these non-ASCII characters cause duplicated
manual pages (under /usr/share/man and /usr/share/man/en).

This patch also modifies man7/glob.7, which uses accented letters in
output.  I have tested that this change is harmless under Debian, but
I do not know for other Linux distributions.
