multiple language sets on a prs-350

[Justice Strike]

I'm trying to get 3/4 languages to work by default.

I'm thinking of either adjusting the default languages or the calibre settings (yes i'm using calibre).

now the thing is i don't want to spent hours tweaking every book i want to upload to my ereader so it has to work by default in the right language.

can i adjust the internal font of the prs350 so that it would pick up the correct font by default?

alternatively can i specify the right font in calibre per "news feed"/book so that i only have to set the chinese/thai/japanese font one time for that feed and not have to change the settings per conversion.

thanks!
