[FIX]: Now supporting legacy encoding schemes – New symbols added – Generation bash script fixed

Now, all the garbage Unicode messages should be fixed. I added support for legacy encoding schemes (Apple), for sources see the individual commit descriptions.

Almost any file has changed as I regenerated all the images in order to retrieve missing Emoji symbols. 3 new symbols are now available for any theme. The bash scripts were broken, since they expected wrong font names (see changes). 

I haven't found out yet if the encoding schemes I support will also cover legacy Android encoding schemes, so there might be more to come. But as for the bugs I've referred to in the issues: Seems to be fixed. :)
