David,
Thanks. It turns out that, once you've set up your locales properly, it's almost impossible to create an example for the problem. I'm working with scientific text which contains a fair amount of symbols: degrees, plus-or-minus, etc. When I read the text in, I specified UTF-8. My locale is UTF-8. Everything would have been alright had wordStem, the stemmer in Rstem, properly processed UTF-8. In fact, though, it did not. It apparently broke up the bytes in the multibyte code for these symbols, so I usually ended up with \xc2 or \xc3. So the problem is clear, and I will circumvent it by removing symbols before stemming.
