But you're right, XwcLookupString() would be the better way since it can deal
with dead keys (as much as XmbLookupString()). Find below the output of xev
when pressing dead-´ and then e, which should be combined to é.
If you don't want to deal with wchar, you could use XmbLookupString() and
handle the backspace and number-of-stars-to-display issues yourself by saving
the number of bytes for each character somewhere.
