Thanks, I will try
question if you can help:
Do you have an idea why the first attempt doesn't work?
I found out, that there is a link
in the original folder of the firmware additional to the 3 fonts. It points to /opt1/dict/SWNMTeb.ttc
In that folder NOTHING can be found (?). If I copy this LINK additional to the 3 font-files in the same folder (which will be mounted at restart) problems partly vanish: no messing up with interface and deleted bookmarks. But:
There is no text visible in the dictionary anymore!
Also described here:
There also is mentioned a solution (?) in just copying a file named SWNMTeb.ttc
instead of the link. A cannot find such a file, not in the firmware nor over the internet.
Once I tried to make my own firmware. I changed one of the fonts – same issue: no text visible in the dictionary.
Besides: I even tried to take the original Sony fonts and mounted it. Same issue: no text in the dictionary. So it shouldn’t be the fonts.
What I cannot understand is the reason of a lot of links in the original firmware pointing to empty folders.
Okay, that's a long question – but maybe you have some ideas.
