The patch convers most literals throughout marconi to unicode. Lietrals not leaving "marconi-land" were left untouched. This is the first patch of a serie that will enforce unicode usage within marconi. Decode early, encode late. String format parameters were left untouched on purpose. Those parameters should be decoded before getting there. Implements blueprint enforce-decoding Change-Id: I85e534ced188191c9c7a17e9908cb720e7d63ca9
