a11450eb04 move some file encodings to UTF-8
* THANKS, doc/ChangeLog-2011, tests/ChangeLog-2011,
  tests/gpg/geheim.txt: convert from iso 8859-1 to utf-8.
* lang/qt/src/dataprovider.cpp, lang/qt/src/qgpgmerefreshkeysjob.cpp,
  lang/qt/src/qgpgmesecretkeyexportjob.cpp: replace U+FFFD REPLACEMENT
  CHARACTER with proper U+00E4 LATIN SMALL LETTER A WITH DIAERESIS.

Note that src/versioninfo.rc.in is still ISO-8859-1.  I don't know
whether Windows will properly handle UTF-8 in this file or not, so i
have not touched it.
