Changing the encoding of these files to UTF-8.

Changing the encoding of these files to UTF-8.
There are some bad constructs on a couple of files (like static arrays of
QStrings initialised directly with const char[] constants, without any proper
decoding) that will most likely break under certain locales.

The encoding is correct. It's the code that must be changed now. I don't
consider this a problem because it was already broken for any locale
different than the one the programmer wrote the code in.
