Simon Willnauer updated LUCENE-2069:
------------------------------------
Attachment: LUCENE-2069.patch
I revised the patch and fixed some issues:
- replaced real characters in tests
- extended tests to boundaries
- Removed "code duplication" in LowercaseFilter
the latter is the most important issue. I figured that if we implement a
factory with the basic codePointAt method based on a version we can implement
the most of the algorithms / methods just by obtaining the version
correspondent instance of CharacterUtils (new class I introduced) What this
class does is pretty simple - if version >= 3.1 it delegates to the Character
correspondent while for earlier versions it convert a character to a codepoint
without checking the for high surrogates. Once we have done this conversion we
can simply use all the Character.*(int) methods as they are.
