Class: utf8
Description
Returns values so that the construction
for p, c in utf8.codes(s) do body end
will iterate over all characters in string s, with p being the position (in bytes) and c the code point of each character. It raises an error if it meets any invalid byte sequence.
(iterator) = utf8.codes(s)
Parameters
s: (string)
Return values
Returns (iterator) iterator
