icu.net

Overview

icu-dotnet is the C# wrapper for a subset of ICU.

ICU is a mature, widely used set of C/C++ and Java libraries providing Unicode and Globalization support for software applications. ICU is widely portable and gives applications the same results on all platforms and between C/C++ and Java software.

NuGet version (icu.net) Build, Test and Pack

Usage

This library provides .NET classes and methods for (a subset of) the ICU C API. Please refer to the ICU API documentation. In icu.net you'll find classes that correspond to the C++ classes of ICU4C.

Although not strictly required it is recommended to call Icu.Wrapper.Init() at the start of the application. This will allow to use icu.net from multiple threads (c.f. ICU Initialization and Termination). Similarly, it might be beneficial to call Icu.Wrapper.Cleanup() before exiting.

Sample code:

    static class Program
    {
        public static void Main(string[] args)
        {
            Icu.Wrapper.Init();
            // Will output "NFC form of XA\u0308bc is XÄbc"
            Console.WriteLine($"NFC form of XA\\u0308bc is {Icu.Normalizer.Normalize("XA\u0308bc",
                Icu.Normalizer.UNormalizationMode.UNORM_NFC)}");
            Icu.Wrapper.Cleanup();
        }
    }

Building

To build the current version of icu-dotnet you'll need .net 6.0 installed.

icu-dotnet can be built from the command line as well as Visual Studio or JetBrains Rider.

Windows and Linux

You can build and run the unit tests by running:

dotnet test source/icu.net.sln

Docker

icu-dotnet depends on libc dynamic libraries at run time. If running within Docker, you may need to install them, for example:

FROM mcr.microsoft.com/dotnet/aspnet:3.1

# Install system dependencies.
RUN apt-get update \
    && apt-get install -y \
        # icu.net dependency: libdl.so
        libc6-dev \
     && rm -rf /var/lib/apt/lists/*

...

ICU versions

Linux

icu-dotnet links with any installed version of ICU shared objects. It is recommended to install the version provided by the distribution. As of 2016, Ubuntu Trusty uses version ICU 52 and Ubuntu Xenial 55.

Windows

Rather than using the full version of ICU (which can be ~25 MB), a custom minimum build can be used. It can be installed by the Icu4c.Win.Min nuget package. The full version of ICU is also available as Icu4c.Win.Full.Lib and Icu4c.Win.Full.Bin.

What's in the minimum build
  • Characters
  • ErrorCodes
  • Locale
  • Normalizer
  • Rules-based Collator
  • Unicode set to pattern conversions

Troubleshooting

  • make sure you added the nuget packages icu.net and Icu4c.Win.Min (or Icu4c.Win.Full).
  • the binaries of the nuget packages need to be copied to your output directory. For icu.net this happens by the assembly reference that the package adds to your project. The binaries of Icu4c.Win.Min are only relevant on Windows. They will get copied by the Icu4c.Win.Min.targets file included in the nuget package.

The package installer should have added an import to the *.csproj file similar to the following:

<Import Project="..\..\packages\Icu4c.Win.Min.54.1.31\build\Icu4c.Win.Min.targets"
    Condition="Exists('..\..\packages\Icu4c.Win.Min.54.1.31\build\Icu4c.Win.Min.targets')" />

Contributing

We love contributions! The library mainly contains the functionality we need for our products. If you miss something that is part of ICU4C but not yet wrapped in icu.net, add it and create a pull request.

If you find a bug - create an issue on GitHub, then preferably fix it and create a pull request!

Package Downloads
SIL.WritingSystems

SIL.WritingSystems contains classes for managing and persisting writing systems using the Locale Data Markup Language (LDML) format. This library also contains classes for processing IETF (BCP-47) language tags and accessing the SIL Locale Data Repository (SLDR).
ParatextData

Dll for use by third party applications needing to access Paratext's data. Compatible with SIL.Lib 12.0.x (required). Backwards compatible with data from Paratext 8.0 and 9.x. NOTE: This version of ParatextData is built using a AnyCPU configuration, but certain projects will not open correctly when run as 32-bit because of dependencies on native 64-bit libraries.
SIL.Windows.Forms.Keyboarding

The SIL.Windows.Forms.Keyboarding library provides cross-platform functionality for keyboard selection and switching in Windows Forms applications. Currently, this library supports system and Keyman keyboards on Windows, and X keyboard extension (XKB) and Intelligent Input Bus (IBus) keyboards on Linux.
