Sorry, will have to move this to 5.0.0 as technically might be a breaking change for those using non-default locale in their applications

Hey @reduckted would you mind rebasing this PR in order to land it in 5.0.0 as soon as 5.0.0-rc.0 is built ?

[reduckted]

Hi @benouat, I've just rebased onto master. Thanks for taking a look :)
