(svn r11981) -Fix [FS#1698]: Use unicode glyph mapping to fix up missing/shuffled sprites in original data files instead of shuffling or skipping

sprites directly. Some required glyphs were not loaded.
-Fix: Large capital U with grave (Ù) along with some other glyphs are broken in the original data files, so do no display them.
