That would not be surprising, and it might even be the best result. The "POSIX_ME_HARDER" argument notwithstanding, a mediocre standard is often better than a proliferation of excellent nonstandards. > Better algorithms with saner results were available years before > UAX#9 was published, and they worked with codepoints from DOS the > codepage 862 just dandy.

Sure, and it's still not usable in any popular editor AFAIK, while millions of people are using the Unicode standard algorithm if it is in fact the one the Microsoft uses in its wordprocessors. Bash and other nonconforming derivatives of the POSIX sh, on the other hand, are in universal use.
