flutter_charset_detector

Automatically detect and decode the charset (character encoding) of text bytes.

The example app; details

This plugin uses native libraries derived from the universal charset detection libraries created by Mozilla.

• iOS, macOS: UniversalDetector2, a thin wrapper around uchardet
• Android: juniversalchardet, a Java implementation of universalchardet
• Web: jschardet, a JavaScript port of the Python chardet

Supported platforms

• Android 4.1 (SDK 16) and higher
• iOS 11 and higher
• macOS 10.14 and higher
• Web (requires TextDecoder support)

Supported charsets

The detectable charsets differ by platform according to the capabilities of the underlying library; for specifics see:

• iOS, macOS
• Android
• Web

Usage

import 'package:flutter_charset_detector/flutter_charset_detector.dart';

Uint8List bytes = getBytes(); // bytes with unknown encoding
DecodingResult result = CharsetDetector.autoDecode(bytes);
print(result.charset); // => e.g. 'SHIFT_JIS'
print(result.string); // => e.g. '日本語'
