There's a new app that allows you to set language, font, and a lot of other stuff on a per app basis.

I have only now had time to look at this. And indeed, one of its functions is the changing of the language options. But... if I want to use this I have to root first. And I don't have any other reasons to do that (yet).

In the mean time I have also looked at how this work. And it seems to come down to a choice by the developer.

In this case the developer has chosen to force FR onto EN system users. (Bad choice... I have deleted the app because of it... )
