I'm using DBD::SQLite to create multilingual FTS databases. I got the unicode61 tokenizer working, but I'm getting an error message when I add remove_diacritics=0 in order to stop the tokenizer from folding ú, ü and ű all into u and so on.
The documentation says: By default, "unicode61" also removes all diacritics from Latin script characters. This behaviour can be overridden by adding the tokenizer argument "remove_diacritics=0". For example: CREATE VIRTUAL TABLE txt3 USING fts4(tokenize=unicode61 "remove_diacritics=0");

Well, that's what I'm doing and I get an error:
DBD::SQLite::db do failed: unrecognized parameter: remove_diacritics=0

Relevant code: 
$dbh->do("CREATE VIRTUAL TABLE tmdata USING fts4 ($collist, tokenize=u
+nicode61)") # works but has undesired side effect of treating all acc
+ented letters the same as the 'base letter'
# $dbh->do("CREATE VIRTUAL TABLE tmdata USING fts4 ($collist, tokenize
+=unicode61, \"remove_diacritics=0\")") # fails with unrecognized para
+meter error
# $dbh->do("CREATE VIRTUAL TABLE tmdata USING fts4 ($collist, tokenize
+=unicode61, remove_diacritics=0)") # fails the same way
return;}

I realize that this is probably a rarely used feature. If nobody has a solution I might email the maintainer (Kenichi Ishigaki).
