This library is available on NuGet: https://www.nuget.org/packages/Diacritics/ Use the following command to install Diacritics using NuGet package manager console:

PM> Install-Package Diacritics

You can use this library in any .Net project which is compatible to PCL (e.g. Xamarin Android, iOS, Windows Phone, Windows Store, Universal Apps, etc.)

The most common use case of this library is to detect and remove diacritic characters from a given string.

HasDiacritics simply tells you if the given string contains any diacritic character. The effort for this check is the same as if you remove the characters using RemoveDiacritics.

// Arrange
const string InputString = "Je veux aller à Saint-Étienne";

// Act
bool hasDiacritics = InputString.HasDiacritics();

// Assert
hasDiacritics.Should().BeTrue();

RemoveDiacritics returns a string for which all diacritics have been replaced.

// Arrange
const string InputString = "Je veux aller à Saint-Étienne";

// Act
string removeDiacritics = InputString.RemoveDiacritics();

// Assert
removeDiacritics.Should().Be("Je veux aller a Saint-Etienne");

The example shown above uses extension methods which use a default implementation of IDiacriticsMapper, namely type DefaultDiacriticsMapper. If you're using an IoC container, you can register IDiacriticsMapper either with the provided DefaultDiacriticsMapper or with your own implementation of IDiacriticsMapper.

Diacritics is extensible! You can write your own language accent by implementing IAccentMapping (or AccentMapping base class). DiacriticsMapper accepts any IAccentMapping type at construction time. You are highly welcome to contribute to this library. Just create a fork, commit your changes and create a pull request.

TODO: Add/Remove methods for adding/removing accents at runtime.
