I talked to mvo about this today. It sounds like there are two ways to deal with this: either bind-mount the desktop locales into the ubuntu-core snap, or bound-mound them into /classic in the ubuntu-core snap and redirect things accordingly. I guess both of these solutions would be done by the launcher.
Note that the same type of thing would need to be done for fonts etc.
> how would a snap access the desktop locales ?
