I was trying to find out what qalter's -r flag does, but I can't search for -r when viewing the man page for it (pattern not found). Yet it's clearly there. If you scroll down a bit you'll see it. Why can't I search for flags in this man page? This online version seems to work fine though.
Can't search for flags in qalter's man page?

It sometimes happens that man pages contain formatting commands and settings that lead to certain characters being rendered using various non-ASCII characters. This can be  instead of |,  (soft hyphen) or  (hyphen) or  (non-breaking hyphen) instead of - (ASCII hyphen-minus),  instead of *, etc.Try searching for non-ASCII characters in the man page:LC_COLLATE=C LESS='+/[^ -~]' man qalterYou can force the man page to be rendered in ASCII by choosing an ASCII character set:LC_CTYPE=C man qalterHaving shell options rendered with a non-ASCII alternative to - is a bug, probably in the man page soucre. I don't know enough *roff to know what the bug might be.
