Actually, it contains the original text in the ISO-2022-JP encoding and
not a unicode representation. You're just storing an anonymous sequence
of characters in your encoded_string variable which you then return.
Any
user interface element that receives these later on has to guess which
encoding is used to represent the text, and it sounds like it can't do
that.

If you're using the text in the GUI, you shouldn't need to pass it
through the codec at all. It should be possible to display the original
string in any widget that can display text. Keep the text in a QString
and
it should just work.
