Can you explain the process with apktool?
Assuming you already have apktool and for the simplicity I renamed Wings XDA 968 Fonts.apk to wingsfont.apk
1) put wingsfont.apk to the apktools folder
2) using command prompt,
apktools.bat decode wingsfont.apk
3) manually delete the fonts file and its xml from the extracted apk which can be found in the subfolder res
4) using command prompt,
apktools.bat build fonts
5) the new apk can be found in dist folder, however it won't install until you sign it.
6) you can use any signer which is available as apk but I used One Click Apk Signer which can be found in xda forum
I think the apktool part can be replaced by using 7zip because the res folder can be seen simply by opening it.
Big thanks to TeamWings for bringing all the fonts to non root users.
