[help-texinfo] Accents in verbatim mode

[spam . spam . spam . spam]

Hello,

I would like to insert text in verbatim mode which use accents.
If I use commands like this : @`{e}, it doesn't work.
If I use the character directly : è, it doesn't work.

I join to this mail a sample to reproduce the problem.
Just download it then, type :
$ texi2pdf accentsverbatim.texinfo
And finally open it :
$ xpdf accentsverbatim.pdf

You see a problem with the accent.

How can I insert an accent here please?

Thank you.
