This approach makes -// the confidence scores more accurate and allows matchers to distinguish -// between variants that are otherwise lost. -// -// As a consequence, two tags that should be treated as identical according to -// BCP 47 or CLDR, like "en-Latn" and "en", will be represented differently.
