A comparison of the 8.2 and 8.3 fuzzystrmatch sources shows no
difference. The behavior of the ascii() function has indeed changed,
but soundex() is no more nor less broken than it was before.
[ thinks for a bit... ] If you are seeing a difference in what soundex
itself does, the most likely explanation is a difference in the behavior
of isalpha() or perhaps toupper(). Are you running on the same
underlying C library as before? Are you quite sure you have the same
encoding and locale selected?
