Hello everybody,

I just attached a (second) series of patches addressing a mix of Unicode
normalization problems to the following bug:


As noted in the “cover letter”:

> This, a couple other fixes, and the addition of the Hangul composition
> algorithm (complementing Gabriel's work on decomposition) causes the
> number of failures in the BMP subset of the Unicode canonicalization
> test suite to drop from 4k+ to 888.
> (Another, still experimental, and more controversial series of mine
> brings that number down to zero, but it still needs a bit of work
> before I post it as an RFC.)

As I'm not sure anybody following that bug has any “free cycles,” I'm
posting the link here for other committers to see.  I would really
appreciate if somebody could have a look at the patches and comment on
what has to be done/changed/improved to get them in Mono.
