I've noticed that even though _\(va_ char (up-down arrow) is defined in a
special font (added with _.special_ request), groff still uses a fallback
which is a combination of _\(ua_ and _\(da_ glyphs (see the attached image).
I've figured out that it happens because the fallback was defined in _ps.tmac_
on line 54:


.fchar \[va] \o'\[ua]\[da]'


I can remove the definition with _.rchar_ request and use a glyph defined in a
special font but I think that groff should use a glygh from a special font by
default. A solution would be to replace _.fchar_ request with _.schar_.

There are other chars defined with _.fchar_ that could also be defined with
_.schar_ instead (like _\(<<_, _\(>>_, _\(ci_ and so on).
