Please don't feed the trolls. If you have to respond to Ranting Rick, at least
write something sensible that people following this thread might learn from,
instead of encouraging his nonsense.
I don't believe for a second you seriously would like len(some_string) to
return '1½', but just in case anyone is taking that proposal seriously, that
would break backwards compatibility. len() must return an int, not a float, a
complex number, or a string.
If you want to know the length of a string *in bytes*, you have to encode it to
bytes first, using some specific encoding, then call len() on those bytes.
If you want to know the length of a string *in code points*, then just call
len() on the string.
If you want to know the height or width of a string in pixels in some specific
font, see your GUI toolkit.
If you want to know the length of a string in "characters" (graphemes), well,
Python doesn't have a built-in function to do that, or a standard library
solution. Yet.
