byte count unicode string

[willie]

# What's the correct way to get the
# byte count of a unicode (UTF-8) string?
# I couldn't find a builtin method
# and the following is memory inefficient.

ustr = "example\xC2\x9D".decode('UTF-8')

num_chars = len(ustr) # 8

buf = ustr.encode('UTF-8')

num_bytes = len(buf) # 9


# Thanks.

buf = ustr.encode('UTF-8')

num_bytes = len(buf) # 9

num_bytes = len("example\xC2\x9D")

This produces 9; isn't that what you want?
If not, please explain, with examples, what you mean by "the
byte count of a unicode (UTF-8) string".

HTH,
John

That is the correct way.
