What is the right way to replace the default Caecilia LT font with a newer version? I got my hands on the new and improved version 5.40 (used in kindle 4.1.0 and kindle keyboard 3.4 - both have identical font files after latest update).
I made "Caecilia LT" directory and renamed:
Caecilia_LT_65_Medium.ttf > Caecilia LT Regular.ttf
Caecilia_LT_66_Medium_Italic.ttf > Caecilia LT Italic.ttf
Caecilia_LT_75_Bold.ttf > Caecilia LT Bold.ttf
Caecilia_LT_76_Bold_Italic.ttf > Caecilia LT Bold Italic.ttf
Then tried to activate it, it told to rebuild cache, I did, it found the new fonts and asked for framework restart. After restart whenever I enter the "Font Hack" application the kindle just reboots.
It created fonts.dir and fonts.scale inside "Caecilia LT" directory and 00-Caecilia LT.conf in /fonthack. When I remove them the Font Hack application starts, but when I activate "Caecilia LT" it behaves just as I described.
Does it need unique names and when I want to use newer version font with the same name this hack can't be used?
