I can't confirm this. At least users of wide builds will see a decrease in
memory use:
$ cat strxfrm_getsize.py
import locale
import sys
print("maxunicode:", sys.maxunicode)
locale.setlocale(locale.LC_ALL, "fr_FR.UTF-8")
words = [
'noël', 'noir', 'nœud', 'noduleux',
'noétique', 'noèse', 'noirâtre']
print("total size of original strings:",
sum(sys.getsizeof(s) for s in words))
print(
"total size of transformed strings:",
sum(sys.getsizeof(locale.strxfrm(s)) for s in words))
$ python3.2 strxfrm_getsize.py
maxunicode: 1114111
total size of original strings: 584
total size of transformed strings: 980
$ python3.3 strxfrm_getsize.py
maxunicode: 1114111
total size of original strings: 509
total size of transformed strings: 483
The situation is more complex than you suppose -- you need less dogma and
more experiments ;)
