Yes and no.

Please read section `Using Symbols' in the groff info manual. While
the notation `\[uXXXX]' intentionally resembles Unicode input
characters, it will return errors for fonts that don't have such
glyphs. If you are using -Tutf8, basically all `\[uXXXX]' work and
are valid.

The glyph index can be found in the affected groff font file. For
example, in special font `S' you can find this line:
u2026 1000,95,17 3 188 ellipsis
However, in `TR' there is
14 750,676,14 2 188 onequarter
The value in the third column is the index. See groff_font(5) for
more.
