Characters outside the 16-bit range aren't supported on all builds. They
won't be supported on most Windows builds, as Windows uses 16-bit Unicode
extensively:
Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit
(Intel)] on
win32
>>> unichr(0x10000)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: unichr() arg not in range(0x10000) (narrow Python build)
Note that narrow builds do understand names outside of the BMP, and
generate surrogate pairs for them:
>>> u'\N{LINEAR B SYLLABLE B008 A}'
u'\U00010000'
>>> len(_)
2
Whether or not using surrogates in this context is a good idea is open to
debate. What's the advantage of a multi-wchar string over a multi-byte
string?
