To automatically convert a language, should you use the value of the keyboard language or location?

Well, I'm from Spain ... I usually have a traditional keying system in Spanish (Aka Spanish International), but sometimes I change it to en_us some tasks ... anyways, the location of my operating system is always in Spanish, even if some applications are in English (because they do not have a Spanish translation Or whatever)

The issue is, if a user has an OS and the environment set for a particular language, usually his favorite language, it is not always right for the keyboard, because some functions have some functions (Such as writing your language in your language for sorting, programming or legacy software, or so on).
