Hi,
Yes, you are asking in the right place!
However, it will be hard to answer exactly, unless you either 1) specify
which line is throwing the exception, or 2) share the whole program so we
can run it for ourselves.
That said, it sounds like maybe a libsoup function is incorrectly annotated
to return a UTF-8 string when it should be returning a byte array?
