CodeBrix.Platform.Unicode

A redistribution of the International Components for Unicode (ICU) version 77 native binaries, packaged as CodeBrix-family NuGet libraries for .NET 10 applications. This repository produces two NuGet packages — one per operating system:

Both are namespace-renamed, .NET 10 ports of their upstream Uno package — intended as drop-in replacements in CodeBrix.Platform-forked Uno applications, and usable in any .NET 10 project that needs the ICU 77 native runtime on the respective OS. The libraries have no managed dependencies other than .NET.

CodeBrix.Platform.Unicode supports applications and assemblies that target Microsoft .NET version 10.0 and later. Microsoft .NET version 10.0 is a Long-Term Supported (LTS) version of .NET, and was released on Nov 11, 2025; and will be actively supported by Microsoft until Nov 14, 2028. Please update your C#/.NET code and projects to the latest LTS version of Microsoft .NET.

CodeBrix.Platform.Unicode (Windows) supports:

• The ICU 77 "common" native runtime DLL (icuuc77.dll) for Windows on x64 and ARM64 — same .dll that upstream Uno.icu-win 77.2.1 ships, byte-for-byte.
• The ICU 77 data shim DLL (icudt77.dll) for both Windows architectures.
• The full ICU 77 data archive (icudt.dat, ~5.5 MB) — covering Unicode collation, normalization, BiDi, character properties, locale (CLDR) data, time zones, transliteration, and the rest of ICU's runtime data.
• A buildTransitive MSBuild .targets pair that automatically embeds icudt.dat as an <EmbeddedResource> at consumer-build time, when the consumer project is a CodeBrix.Platform head ($(IsCodeBrixHead) == 'true') and the data has not yet been embedded by another package in the same build ($(CodeBrixIcuDataIncluded) != 'true'). A second target in the same .targets copies icudt.dat beside the output of non-head Exe/WinExe consumers (test projects, console tools); class libraries get neither route.

CodeBrix.Platform.UnicodeMacOs supports:

• The ICU 77 "common" native runtime library (libicuuc.dylib) for macOS as a universal binary (x86_64 + arm64, one file for Intel and Apple-silicon Macs) — same .dylib that upstream Uno.icu-macos 77.2.1 ships, byte-for-byte.
• The ICU 77 data shim library (libicudata.dylib), also universal.
• The same full ICU 77 data archive (icudt.dat) — byte-identical to the one in the Windows package.
• The same auto-embedding buildTransitive MSBuild .targets mechanism, using the same $(IsCodeBrixHead) / $(CodeBrixIcuDataIncluded) properties — so a build that somehow sees both packages (or an upstream Uno.icu-* package) still embeds icudt.dat exactly once.

Sample Usage

These are runtime-binaries packages. Add the one matching your target OS and the ICU native libraries are made available to the runtime via the standard NuGet runtimes/<rid>/native/ mechanism.

# Windows apps:
dotnet add package CodeBrix.Platform.Unicode.ApacheLicenseForever

# macOS apps:
dotnet add package CodeBrix.Platform.UnicodeMacOs.ApacheLicenseForever

For Uno-fork apps that previously used Uno.icu-win or Uno.icu-macos, the migration is a NuGet-reference swap — no managed-API change is required, since neither these packages nor their upstreams expose a managed API.

Migrating from Uno.icu-win

Replace the <PackageReference Include="Uno.icu-win" Version="77.2.1" /> line in your csproj with <PackageReference Include="CodeBrix.Platform.Unicode.ApacheLicenseForever" Version="{current version}" />. The MSBuild property names are renamed from upstream (IsUnoHead → IsCodeBrixHead, UnoIcuDataIncluded → CodeBrixIcuDataIncluded); a CodeBrix.Platform head sets IsCodeBrixHead, so the embedded-resource trigger fires without any change to the consuming project.

Migrating from Uno.icu-macos

Replace the <PackageReference Include="Uno.icu-macos" Version="77.2.1" /> line in your csproj with <PackageReference Include="CodeBrix.Platform.UnicodeMacOs.ApacheLicenseForever" Version="{current version}" />. The same renamed MSBuild property names apply.
