This is similar to https://gerrit.omnirom.org/#/c/14014 A lot of the features built in the older patch set have been split out into separate patches, most of which have already been merged. The remaining functionality here should all be directly related to language selection and loading. We always load English as a base before loading other languages over the top of the base. The idea is that if another language is missing a translation, then we will still display the English. Maybe still to do: read the /cache/recovery/last_locale file and load a language based on that. For me, this file contains just: en_US We probably won't bother with region specific translations so we would have to look at either trimming off the _US or using some other method like perhaps a symlink or a combination of the two. Thanks to _that for twmsg.cpp class Change-Id: I9647a22e47883a3ddd2de1da51f64aab7c328f74
