QregExp: matching accented letters

[bred]

I need for a regular expression that match the accented letter (or special letters) like (éèà ìüäöçã .... )

1) There exists some abbreviation or a range for simplify the work.
2) For setting up the regex it's possible to write:

reg.setPattern( QString::fromUtf8( "[éèà ìüäöçã]" ) ) ;
