I'm afraid my English-centricity is showing, but I could use a little
help filling in the missing examples in the table here:
http://developer.postgresql.org/pgdocs/postgres/textsearch-parsers.html
I'm not sure of a suitable example all-non-ASCII-letters word, and
even less sure of how to represent it in SGML. (I remember we had
quite a bit of trouble dealing with accented letters in people's names,
for instance.)
