I applied this to the 2.2 branch in r3747, so it'll appear in the 2.2.2 release.  I added error handling support to the java bridge in addition to what was already in the patch, so setting replace and ignore works now.  Unfortunately, the user defined error handling functions added to Python 2.3 require more information and control over the encoding process than Java's error handling hooks provide, so this can't be directly applied to trunk and some more work will need to be done to keep Japanese codec support going forward.  Probably the easiest course of action is to pull over a version of this code that just rejects non-builtin error handling types.
