Hello, are there special characters missing in groff? I get the following warnings in an UTF8 locale:
$ tbl /usr/local/share/man/man7/groff_char.7|nroff -mandoc >/dev/null /usr/local/share/man/man7/groff_char.7:811: warning: can't find special character `\o' /usr/local/share/man/man7/groff_char.7:1038: warning: can't find special character `bs' /usr/local/share/man/man7/groff_char.7:1179: warning: can't find special character `radicalex' /usr/local/share/man/man7/groff_char.7:1182: warning: can't find special character `sqrtex'
