API strlen

Return the length, in bytes, of the string passed. string.len(s) strlen(s)

s = "Lua" print(string.len("Lua"), s:len, #s) -- 3,3,3; the three methods are equivalent print(string.len("Lua\000user")) -- 8: Lua strings are 8 bit pure so \000 does not terminate

• - for utf8-aware string length parsing.
