# RE: UNICODE STRING HANDLING
|
||||
#
|
||||
# Python distinguishes between the str (string of bytes)
|
||||
# and unicode (string of code points) types. Most operations
|
||||
# work on either one just fine, but some (like regexp matching)
|
||||
# require unicode, and others (like write) require str.
|
||||
#
|
||||
# As befits the language, Python hides the distinction between
|
||||
# unicode and str by converting between them silently, but
|
||||
# *only* if all the bytes/code points involved are 7-bit ASCII.
|
||||
# This means that if you're not careful, your program works
|
||||
# fine on "hello, world" and fails on "hello, 世界". And of course,
|
||||
# the obvious way to be careful - use static types - is unavailable.
|
||||
# So the only way is trial and error to find where to put explicit
|
||||
# conversions.
|
||||
#
|
||||
# Because more functions do implicit conversion to str (string of bytes)
|
||||
# than do implicit conversion to unicode (string of code points),
|
||||
# the convention in this module is to represent all text as str,
|
||||
# converting to unicode only when calling a unicode-only function
|
||||
# and then converting back to str as soon as possible.

if type(s) != t:
