... and the Unicode integration made that a reality :-)

In todays globalized world, the only sane way to deal with
different scripts is through Unicode, which is why I
believe that text data should eventually always be stored in
Unicode objects - regardless of whether it takes more memory
or not.

(If you compare development time to prices of a few GB extra
RAM, the effort needed to maintain text in non-Unicode
formats simply doesn't pay off anymore.)

Ah, now I know where you're coming from :-) Shift tables
don't work well in the Unicode world with its large alphabet.

BTW, you might want to look at the BMS implementation I did
for mxTextTools. Here's a nice reference for pattern
matching:
