Simon, yeah i just checked.
all the properties, behind the scenes are stored as int.
we shouldn't use any char-based methods pretending it will buy us any faster performance.
it will just make the code ugly and probably slower.

slower meaning, the "if" itself in the lowercasefilter patch, it can now be removed.

> CharArraySet does lowercaseing if created with the correspondent flag. This causes that
 String / char[] with uncode 4 chars which are in the set can not be retrieved in "ignorecase"
mode.
