Description

Iterate though the UTF-8 string s. If only s is given, it can used as a iterator: for pos, code in utf8.next, "utf8-string" do -- ... end if only charpos is given, return the next byte offset of in string. if charpos and offset is given, a new charpos will calculate, by add/subtract UTF-8 char offset to current charpos. in all case, it return a new char position (in bytes), and code point (a number) at this position.

(varies) = utf8.next(s,charpos,offset)

Parameters

s: (string)
charpos: (number) optional
offset: (number) optional

Return values

Returns (varies) next iteration
