# 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.
def typecheck(s, t):
if type(s) != t:
raise util.Abort("type check failed: %s has type %s != %s" % (repr(s), type(s), t))
