The image file: cramfs.rootfs.img in the package is NOT encrypted. So some respectful member of this forum may be able to make customized img file with neccessary fonts included. I am interested in Chinese fonts. Or actually I like the approach of only mount font directory without flashing.
Thanks for anybody making this possible!
