localization, internationalization decimal-separator

[inox99]

is it possible to setup sprintf to format due to a language-specifier (e.g."fr", "es", "de") to have the output accordingly? So:
console.log(sprintf("%0.2f", 1.23456789)); to print
1.23 for "en"
1,23 for "de"
either by choosing a language-specifier or by setting the decimal-separator-character?

I also need this. As far as I can see, this is currently not possible. As a workaround, I'm replacing a '.' with a ',' after formatting (I'm only using the library for very simple use cases).
