first of all.... you dont need to copy your font to usr/share/fonts folder manually.... just use theme customizer & import the font from any folder you put in...open TC & click on the status bar...there an option to import font from folder...that is the proper way to do it on the first place.... second....as i read from pages 1 you didnt mention (or i didnt see it) did you try restoring the theme to it default??? you should try it & see what will happen.... third....if the problem still persist then use filebox,winscp or open SSH & go to.... home/user/.fontconfig (delete all config files) usr/var/cache/fontconfig (delete all files) after deleting all files reboot your phone & see the effects.... your font will be back to normal if you do it correctly...
