**Is your feature request related to a problem? Please describe.** I'm trying to understand why Rec. 2020/2100 PQ JPEG XL files exported from Lightroom Classic sometimes show up with the...

ICU4X Locale capabilities should enable implementation of CSS lang()

3

Currently ICU4X `Locale` supports UTS 35, [which excludes parts of BCP 47](https://www.unicode.org/reports/tr35/#bcp-47-conformance), specifically "non-canonical", "irregular", or "privateuse". In https://bugzilla.mozilla.org/show_bug.cgi?id=1857742 , Gecko restored support for these non-UTS 35 deprecated tags in...

Document considerations related to lowering the collation strength from the default

Inspired by discovering how Firefox and Thunderbird UI code uses collation and pondering whether it makes sense.

CollatorBorrowed should have an infallible constructor from baked data

8

AFAICT, the only way for `CollatorBorrowed::try_new` to fail is to override baked data with badly-generated baked data. It seems to me that broken baked data is a different category of...

Consider making root-collation CollatorBorrowed const-constructible from baked data

3

If `CollatorBorrowed` was `const`-constructible, it would be possible to have a `CollatorBorrowed`-typed `mut static` (without wrapping in `Option` or `MaybeUninit`) that could be overwritten with a dynamically-initialized `CollatorBorrowed` from `main`.

Fall back to parsing environment variables if setlocale reports C

1

ICU4X currently has code for obtaining system locale settings by calling POSIX `setlocale` with the null pointer as the second argument. However, this always says `C` unless the application has...

Consider special-casing year 1906 in the Chinese calendar

2

According to https://github.com/dotnet/runtime/blob/1d1bf92fcf43aa6981804dc53c5174445069c9e4/src/libraries/System.Private.CoreLib/src/System/Globalization/ChineseLunisolarCalendar.cs#L34 how the months of the Chinese calendar were actually used in 1906 differs from Reingold's math. Decide if the calendar offered by ICU4X is meant to match...

Graduate API for Date::added() and Date::until()

5

Temporal requires https://tc39.es/proposal-temporal/#sec-temporal-calendardateaddition and https://tc39.es/proposal-temporal/#sec-temporal-calendardatedifference , but these are unstable hidden APIs in ICU4X. For Temporal compat, we need public API surface for these. Sub-issues: - [ ] https://github.com/unicode-org/icu4x/issues/7059 -...

Mapping from BCP47 extensions to collator options is inconsistent

14

Currently, the option [enum re-exports in the collator](https://github.com/unicode-org/icu4x/blob/main/components/collator/src/lib.rs#L325) look like this: ```rust pub use icu_locale_core::preferences::extensions::unicode::keywords::CollationCaseFirst as CaseFirst; pub use icu_locale_core::preferences::extensions::unicode::keywords::CollationNumericOrdering as NumericOrdering; pub use icu_locale_core::preferences::extensions::unicode::keywords::CollationType; pub use options::AlternateHandling; pub use...
