// This converts a Chrome language code to the Translate server synonym. The
// only translate language codes with a country extension are zh-TW and zh-CN,
// the country code is striped from all other languages. Does not check if the
// base language is translatable. Please keep consistent with the same logic in:
// chrome/browser/resources/settings/languages_page/languages.js,
void ToTranslateLanguageSynonym(std::string* language);

// Converts language code synonym to use at Chrome internal.
