  1. Correct tests for Unicode Language Identifier 

    The underscore character "_" is only accepted for the sep production [1]
when the backwards-compatibility extensions [2] are enabled. However,
ECMA-402 only accepts Unicode BCP 47 locale identifiers [3], meaning
identifiers *without* the backwards-compatibility extensions.
