contains(translate($cont, $alpha, 'x'), 'x')

I've heard that string-length() can get expensive because of
multi-byte characters, although I would've thought translate()
sufferered from the same problem...

It might, although it's never slowed down any of my stylesheets so as to notice. :->

In any case, translate() is fun -- the secret-decoder-ring function, with all kind of nifty uses.
