Title: Formerly, when converting a b_encoded string...

...from encoding like 'GB2312', 'BIG5', or 'ISO-8859-6' to 'UTF-8' an error would be thrown if a character did not exist in the 'UTF-8' encoding. Now the character
will be replaced with an empty character instead of throwing the error.

Note that previously if a b_encoded character did not exist in the input encoding, it would be replaced
with an empty character in the output. This change adds the same functionality if the character
does not exist in the output encoding.
