I would actually expect to see std::wstring here - the conversion to UTF-8 is an
implementation detail of libadblockplus.

[Felix Dahlke, 2013/06/26 09:32:55]

Yes, that seems to make more sense, since the plugin works with UTF-16
internally. However, all the other methods have std::string in their signatures,
so I opted for that. I suppose it makes sense to change all of that to
std::wstring, would rather to that in a separate commit though.

[Wladimir Palant, 2013/06/27 05:55:02]

Yes, the other methods seem wrong as well. I'm fine with changing it all later
then.
