In a utf-8 locale, nroff defaults to the utf8 device, which is why the
nroff example as written did not work for you.

It seems that you need support for u0075_030A in the groff font file if
you want to use the unicode combining sequence.

This:

:; grep u0075_030A /usr/share/groff/1.22.2/font/*/R
/usr/share/groff/1.22.2/font/devhtml/R:u0075_030A       24      0       0x016F
/usr/share/groff/1.22.2/font/devutf8/R:u0075_030A       24      0       0x016F

shows that only those two devices have it by default.

The aring example worked because the font/devps/TR file has explicit
support for the type1 /aring glyph.  It also support the /ring glyph,
so maybe something like:

    \o'u\C\'ao\''

is the way to go?  \o'' overstrikes up to nine glyphs; \C'ao' is the ring glyph.

It works here for ps, dvi and pdf devices.  But only for troff; nroff
only show the last glyph from the \o'' set.

(I used http://cm.bell-labs.com/sys/doc/troff.pdf to learn \o'' and \C''
and looked at /usr/share/groff/1.22.2/font/devps/TR to find the roff
name (ao) for the ring glyph.)
