Add additional assertion to branding tests for proposal-intl-locale-info
to make sure they don't pass spuriously when the proposal is not
implemented.
It is incorrect to expect the minimize result of "zh-Hant" to be "zh-TW". It should be "zh-Hant". Why?
first, what we have in input for zh-Hant
lang = zh
region = [none]
script = Hant
Now, look at the AddLikelySubtags algorithm in http://www.unicode.org/reports/tr35/#Likely_Subtags
With the move to UTS 35 for language tag processing, the expected
canonicalisation results for "cel-gaulish" should now be consistent across
implementations.
These two slipped through the cracks in #2097:
test/intl402/Intl/getCanonicalLocales/non-iana-canon.js
- Variant subtag canonicalisation is currrently not allowed.
test/intl402/Locale/getters.js
- Only the first "loc.caseFirst" test in this file was updated in #2097.
constructor-non-iana-canon.js
- Variant subtag canonicalisation is currently no longer present.
constructor-options-region-valid.js
- Digit region codes are now canonicalised.
constructor-tag.js
- Variant subtags are now sorted alphabetically.
likely-subtags-grandfathered.js
- "cmn" is now canonicalised to "zh".
Per https://tc39.github.io/ecma402/#sec-canonicalizelanguagetag
6.2.3 CanonicalizeLanguageTag ( locale )
The CanonicalizeLanguageTag abstract operation returns the canonical and case-regularized form of the locale argument (which must be a String value that is a structurally valid Unicode BCP 47 Locale Identifier as verified by the IsStructurallyValidLanguageTag abstract operation). A conforming implementation shall take the steps specified in the “BCP 47 Language Tag to Unicode BCP 47 Locale Identifier” algorithm, from Unicode Technical Standard #35 LDML § 3.3.1 BCP 47 Language Tag Conversion.
And

"
2. If the BCP 47 primary language subtag matches the type attribute of a languageAlias element in Supplemental Data, replace the language subtag with the replacement value.
If there are additional subtags in the replacement value, add them to the result, but only if there is no corresponding subtag already in the tag.
