Indeed.  I think this is a bug in groff: The devutf8 font files don't
contain non-spacing glyphs.  If you manually enter the line

  u0301   0       0       0x0301

to the *installed* utf8 device files `.../font/devutf8/{R,I,B,BI}',
the problem vanishes.  Similar lines would be necessary for all other
latin, non-spacing glyphs.

Note that currently the script `font/scripts/genfonts.sh' doesn't
handle an entry `0' in the second column correctly, always overwriting
it with `24' for devutf8; this prevents the proper solution to fix
`font/devutf8/R.proto' directly.

PS: It seems that the files `dev{utf8,html}/R.in' are no longer in
    use.
