finding turkish characters in like expression

[lantis system <la...@gmail.com>]

hello all...
 
i use memory expression and filter.  FilterObjects returns an empty list if the expression to be filtered has Turkish characters.

For example
Expression exp = XXX.yyy.likeIgnoreCase('%turkish characters(\u011fü\u015fiöç\u011eÜ\u015e\u0130ÖÇ)%')

and 

List list = exp.filterObjects(mylist) ; 

Unfortunately list result  is empty.   


Thank you in advance

Hi there,

I suspect there may be a bug in Cayenne. When building a match Pattern we are using Pattern.CASE_INSENSITIVE flag, while we should probably be using (Pattern.CASE_INSENSITIVE | Pattern.UNICODE_CASE). We'll investigate.

In the meantime can you please confirm that "match(..)" and "like(..)" expressions work for you? This will narrow the problem to just case-insensitive like.

Thanks,
Andrus
