Add in-tree normalization benchmarks

2

I have [out-of-tree normalization benchmarks](https://github.com/hsivonen/norm_bench) that use Wikipedia content and that take a rather long time to run. So far, experience suggests that English and Greek normalization performance are particularly...

Refactor the upcoming buffer in the collator

3

`CollationElements::upcoming` currently holds `CharacterAndClassAndTrieValue`. Logically its last element (when not at the end of the stream) needs to hold `CharacterAndTrieValue` (which currently doesn't exist in the collator but exists in...

Experiment with pointer-based slice prefix computation in normalizer

3

#2378 uses a pattern where there is a full slice and another slice that's known to be its suffix, and the prefix of the full slice is computed either so...

Use extend() with iterator as appropriate in normalizer and collator

5

[Instead of pushing in a loop, use extend.](https://github.com/unicode-org/icu4x/pull/2481#discussion_r958400225)

Provide glue code for HarfBuzz

1

[`icu_normalizer::properties`](https://unicode-org.github.io/icu4x-docs/doc/icu_normalizer/properties/index.html) has API surface whose purpose is to cater to HarfBuzz. Additionally, `icu_properties` has functionality required by HarfBuzz. [`hb-unicode.h`](https://searchfox.org/mozilla-central/source/gfx/harfbuzz/src/hb-unicode.h) defines the callbacks that need implementations. These are C-linkage function pointers,...

Add CharULE::from_array<N>(chars: [char; N]) -> [CharULE; N]

4

Add const-evaluable `CharULE::from_array(chars: [char; N]) -> [CharULE; N]`. (I'm not sure if const evaluation is powerful enough to do this.)

(It was previously concluded in a meeting that it's not a post-1.0 breaking change to switch from bogus data causing GIGO to bogus data causing a constructor to err out.)...

Since this appears to be...

Returning non-UTF-8 charset from getDefaultMIMECharset() provides negative value these days

5

[`getDefaultMIMECharset()`](https://github.com/eclipse-ee4j/javamail/blob/beab9265aa39a4c3c4a2e220b1e4c198060803a5/mail/src/main/java/javax/mail/internet/MimeUtility.java#L1316) tries to use a charset from a system property and falls back on the system encoding. It would make more sense to use UTF-8 unconditionally. MUAs have been able...

Consider supporting retrieval of the language preference list from the system

30

Consider providing functionality (with `std`, not with `no_std`) for retrieving the user's system-level preference list of languages as ICU4X locales. On Windows, Gecko prefers https://learn.microsoft.com/en-us/uwp/api/windows.system.userprofile.globalizationpreferences.languages?view=winrt-22621#windows-system-userprofile-globalizationpreferences-languages and adds region with likely...
