    Affects Versions: 1.3

            Priority: Trivial

In the above thread, it was suggested to extend the SpellingQueryConverter to 
cover the full UTF-8 range instead of handling US-ASCII only. This might be as 
simple as changing the regular expression used to tokenize the input string to 
accept a sequence of one or more Unicode letters ( \p{L}+ ) instead of a 
sequence of one or more word characters ( \w+ ).

See http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html for 
Java regular expression reference.
