UniversalCharsetDetection

A Swift wrapper around the uchardet library to detect the character encoding of a sequence of bytes.

uchardet is more versatile than NSString.stringEncoding(for:encodingOptions:convertedString:usedLossyConversion:) because

• it supports many more encodings;
• it supports streaming large files; and
• its output is compatible with iconv.

Usage

Compatible with Swift 4.2+.

• To integrate the library into your project, add a dependency on this package in your project’s Swift Package Manager configuration file or in your Xcode 11+ project.
• To detect the character encoding of a file, see CharacterEncodingDetector+File.
• To detect the character encoding of a collection of bytes, see DataProtocol+CharacterEncoding.
• To detect the character encoding of a manually-provided stream of bytes, see CharacterEncodingDetector.

Contributing

Since the Swift Package Manager does not yet support binary dependencies, we copy the uchardet source code into the Sources/Cuchardet directory to enable the Swift Package Manager to build and link with the uchardet library. See the adapt-uchardet-to-swiftpm script.

To change the version of the uchardet library, run the following commands in the root of the source code directory tree:

$ git init uchardet
$ git submodule update --remote uchardet
$ cd uchardet
$ git checkout <master or tag name>
$ cd ..
$ ./adapt-uchardet-to-swiftpm
