Method string_to_utf8()

Method string_to_utf8

string(8bit) string_to_utf8(string s)
string(8bit) string_to_utf8(string s, int extended)


Converts a string into an UTF-8 compliant byte-stream.


Throws an error if characters not valid in an UTF-8 stream are encountered. Valid characters are in the ranges 0x00000000-0x0000d7ff and 0x0000e000-0x0010ffff.

If extended is 1 then characters outside the valid ranges are accepted too and encoded using the same algorithm. Such encoded characters are however not UTF-8 compliant.
