Re: [Ietf-languages] Suggestion to update Urdu Script Designation in the subtag registry

CLDR does have likely subtags, which provide default interpretations for
incomplete language tags.

For Hausa, the default script varies by region.

Richard, these are all 'best available data', and are continually being
refined. It is especially a problem for longer-tail languages. Where there
are howlers, we'd like to know about them. Saurashtra is still an issue
(see the above page), but I see no bug report with the term "Saurashtra",
except for the following 2, which appear unrelated.

Could you file a bug report for Saurashtra and any other cases you know of?
