The relevant standard is BCP 47: https://tools.ietf.org/html/bcp47

The standard separator is hyphen (-), but use of underscore is common. 
POSIX locales, for example, use underscore. I guess hyphen should be 
preferred, but we should accept underscores and map them to hyphens. In 
any case, they are treated identically and underscore is never permitted 
by BCP 47, so folding them together as hyphens is safe.
