It is done automatically when the translator for that language runs the
uplang script to import the new strings into the language file. Before
that happens, the english strings will be used by Rockbox.

It is nobodys responsibility, but anyone that feels like it can create a
new voice file and upload it to the wiki.

Well, the "off-screen" icons are not customizable. All you can do is to
define a new character to be included in the character map. This isn't
very usable for the A/B repeat, since the repeat status isn't shown
using characters, but rather the "off-screen" repeat icons. IIRC, there
are only icons for repeat and repeat-1 :-(.

You can leave that to us. It looks like ON and the -/+ are free on the
player. I don't know about the Ondio though.

The "cleanest" way would probably be to implement it in the MP3 thread,
but that involves quite a lot of tricky work. Let's do it your way
first, and then improve it if we need to.

Thanks for working on this!
