Known issue. From http://www.sqlite.org/lang_expr.html on the 'LIKE' operator: SQLite only understands upper/lower case for 7-bit Latin characters. Hence the LIKE operator is case sensitive for 8-bit iso8859 characters or UTF-8 characters. For example, the expression 'a' LIKE 'A' is TRUE but 'æ' LIKE 'Æ' is FALSE.) This isn't the exact problem you're having, but the point is that SQLite is not very Unicode aware, beyond correctly supporting encoding and decoding. And that's to be expected, given the huge complexities of dealing with different languages. The good news is that you can re-implement the LIKE function fairly easily. There have been a number of posts in the past dealing with using external Unicode/I18N libraries to implement a more complete 'LIKE' function. -j -- Jay A.
