This method converts the given string to a sequence of bytes using the given charset and returns an array of bytes. So, while this is almost identical to the first example, I just want to add it here as an example. For example: If you do this, of course you'll have to reverse the conversion on the decoded string: See also the example utf8_to_b64 and b64_to_utf8 functions in the Solution #1 escaping the string before encoding it section of the Base64 glossary entry.
