I tried Georgia and Avenir are placed in the system folder usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts

These actions are no longer needed:

   • Press the [Aa] font menu button. You don't need to do anything else, just close it again.
   • If you still don't see the font, force the Kobo to re-render by paging across a chapter file boundary, then page back again. Or, closing the book and opening a different one might work, too.

font is displayed immediately.

Checked on firmware 4.21

Actual for those who replace Avenir or Georgia, placing your font mnt/onboard/font/ folder.

Fonts can be replaced using kobopatch.

Yeah, the Kobo QPA will attempt to open every font in there (and more) on startup, so this makes sense .

I tried your suggestion on a KA1 with fw 4.21, but couldn't get it to work.

I used this as the 'files' section of kobopatch.yaml. Is there something obviously wrong with it? Obviously I removed the custom fonts from the user-accessible /fonts directory before I started.

@jackie_w: The second 'T' ought to be lowercase in "Trolltech" .

(EDIT: And, for future readers: case matters here (i.e., font filenames, too). This lives on a case-sensitive filesystem, unlike the USB partition).

Unbelievable I blame Lockdown.

@Semwize,

Good discovery! It works well when once I stopped being an idiot.

I'll have a think about how to change posts #1, #2 and the summary in #63 to reflect the new info.

Did you ever try this on earlier firmwares and, if so, what happened? I remember reading long ago that it didn't work, the encryption/obfuscation was mentioned. I just took this at face value and never actually tested it for myself.

[jackie_w]

@NiLuJe,

Not being a Linux user I don't know how to interact directly with the Kobo file system. Is there some way I can remove the superfluous usr/local/TrollTech directory I just created in error? I know it's easy to add files but I'm not sure how to remove them. Luckily my KA1 is only a test device these days, so no real harm done.

Of course I checked, and it did not work. But I did not check firmware 4.20. Just need to ask NiLuJe which version of the firmware this made possible.

[NiLuJe]

@Semwize: I wouldn't really know, I only noticed that when looking into something totally unrelated on a whim, and that was on 4.20 also .

@jackie_w: You could stick a rm -rf "/usr/local/TrollTech" in a NickelMenu command_spawn or command_output. (Taking care not to make a typo on this one, because that would be bad ^^).

(Alternatively, you can also let it lie, there should be enough of a buffer of free space available in there for quite a few stray files ).

Hmm. Maybe I'll just leave it alone for now.

Speaking of space ... if someone tried to replace the 4 stock Georgia .ttf files with much bigger ttfs would you anticipate some level of risk?

No, you missed my point. I meant MUCH bigger, e.g. Code2000 (8Mb) or ArialMSUnicode (23Mb)

With a large set of glyphs. Need to check.

For a dictionary, not to use a patch to change? I would not do it. The menu is configured for Georgia and Avenir.

[NiLuJe]

There's (currently) ~70MB of free space in the rootfs on a stock device, you have quite a bit of leeway .
