I'd agree that, right now, acting on code points outside the BMP
shouldn't be needed. Providing other characters are passed through, it
will cope happily with anything I can reasonably think of throwing at
it :-)

So when you were talking about strings being in UTF-8, were you
talking about input and output only? I wasn't awarethe concept of
'string' applied to anything other than things in the Snowball
language itself ... or do you mean that strings would be stored
internally to a running snowball stemmer in UTF-8?
