unicodedata.east_asian_width(). You can still implement your own
simple width() function using it like this:
def width(u):
w = 0
for c in unicodedata.normalize('NFC', u):
cwidth = unicodedata.east_asian_width(c)
if cwidth in ('W', 'F'): w += 2
else: w += 1
return w
iswide() for east asian width manipulation. (Inspired by David

- Move _PyUnicode_TypeRecord.flags to the end of the struct so that
no padding is added for UCS-4 builds. (Suggested by Martin v. Loewis)
- use unidb compression for the unicodectype module. smaller, faster,
and slightly more portable...
(note: this commit doesn't include the unicodectype.c file itself; I'm
still waiting for the reviewers...)
