I'm impressed at the number of downloads this patch is getting.
Obviously there's plenty of interest in this topic.

Folk who use the hexdump(1)/od(1) utility (in particular "od -c")
to examine files will encounter a problem after applying the
lcctype.patch.

There's an assert check in hexdump/conv.c:137 that verifies that
the character has (width > 0).  This assertion is no longer valid
once you've listed bunches of characters with SWIDTH0.  If you
run "od -c" on a file containing utf-8 combining characters, the
assert test will fail causing od to dump core.

I also have a patch for this and this patch is now documented
here:
