We were duplicating the Unicode/code page mapping table between txt_gui.c and txt_sdl.c, but in an incomplete and inconsistent way. It makes sense that the code page mapping should be kept with the font files that represent the code page anyway, as there may be projects like Julian Nechaevsky's Russian Doom which may want to change the code page.
