It's definitely a bug in  utf8accents.sty  .
The accented empty {} just doesn't work -- for any accent.
I've tracked this and have a fix.

However, I might as well fix the other things too,
according to the discuss last week, or whenever it was.

That is, ...

  ... I can make \~{} give the accent character  Ux0C2D
  (as \textasciitilde  gives now )
and make  \textasciitilde  give the full-size tilde  Ux00E7 .

This way both tilde characters are accessible.
Do you agree that this is the best approach ?


Jonathan, and others --- opinions please.


Cheers

	Ross
