1531091 - Don't drop Unicode extension keys without values when resolving locales

Status: RESOLVED FIXED

(Core :: JavaScript: Internationalization API, enhancement)

Description

[Jeff Walden [:Waldo]]

Change from https://github.com/tc39/ecma402/issues/223 with test modified in https://github.com/tc39/ecma402/pull/302 and as soon as I update test262 enough, we'll be failing this test. Filing now to get a bug number to add to the jstests.list skip-entry.

Attachment: Bug 1531091: Append Unicode extensions without values and remove "true" value from keywords. r=jwalden!

• Implement the spec changes from https://github.com/tc39/ecma402/pull/302.
• Additionally for the test262 test to pass, we also need to implement parts of
  the Unicode extension canonicalisation from bug 1522070. Namely removing the
  value "true" from keywords.
• The two helper functions were copied from the Intl.Locale patch.
• CanonicalizeUnicodeExtension was slightly modified to allow duplicate
  keywords, which is required by spec.
