Hi TeXers,
I've got stuck in hyphenation of "accented" words:
I would like to hyphenate words with some letters underbared;
I tried

\def\u#1{\underbar{#1}\penalty10000\hskip 0pt plus 0pt}
\showhyphens{preposterous prep\u{o}sterous}

and \TeX\ answered ``pre-pos-ter-ous prep$[]$sterous''

but this is preposterous for me. (And I don't want to insert
every hyphenation point by hand). Does there exist a way to
proper solution of this problem inside \TeX's mouth?

I thought of using virtual fonts (I would like to use postscript
fonts), but I chucked up the sponge -- I wasn't able to find
more about the "VPL language". Is the .WEB file of VPTOPL the only
document describing it? Does there exist a simple way of
inserting postscript or \TeX\ code (underbar should have the width
of the letter) into a virtual character? Does there exist any
tool for that? Another problem with this approach is that I would
have to modify hyphenation patterns.

Are there features in multilingual TeX to solve the problem?
emtex beta 7 implemented \charsubdef primitive. Where is it
described? May it help solve the problem?

Any suggestions which way to go through?
Please post directly to me, I'll summarize for the group.
