Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

Enough Convert extends Dart's built-in `dart:convert` with support for additional character encodings such as ISO 8859, Windows, DOS, GBK, Big5, and KOI8 R/U. It fills gaps in handling legacy and non-UTF-8 text formats commonly used in internationalized applications. Ideal for parsing or generating text in older systems or region-specific encodings, this package ensures accurate data processing across diverse environments.

Use cases

  • Parsing legacy text files with non-UTF-8 encodings
  • Handling multilingual content in regional character sets
  • Converting between different codepages in desktop and mobile apps
  • Processing data from old systems using DOS or Windows encodings
  • Supporting East Asian text (GBK, Big5) in internationalized apps
  • Ensuring correct display of Cyrillic text (KOI8-R/U)

Key features

  • Supports ISO 8859, Windows, DOS, GBK, Big5, and KOI8 encodings
  • Lightweight and compatible with all Flutter platforms
  • Simple API extending `dart:convert`
  • No external dependencies
  • Accurate encoding/decoding for legacy formats
  • Cross-platform consistency

Suitable for

  • Developers working with legacy data sources
  • Apps requiring multilingual text support
  • Projects involving East Asian or Cyrillic character sets
  • Mobile and desktop apps needing codepage conversion
  • Internationalization teams handling non-UTF-8 content

Considerations

  • Not needed for UTF-8-only workflows
  • Limited to specific legacy encodings
  • May require knowledge of target encoding standards
  • Performance impact negligible but present for large-scale conversions
  • Best used when dealing with known non-UTF-8 input/output

Usage

Using enough_convert is pretty straight forward:

import 'package:enough_convert/enough_convert.dart';

main() {
  final codec = const Windows1252Codec(allowInvalid: false);
  final input = 'Il faut être bête quand même.';
  final encoded = codec.encode(input);
  final decoded = codec.decode([...encoded]);
  print('${codec.name}: encode "$input" to "$encoded"');
  print('${codec.name}: decode $encoded to "$decoded"');

}

The latest version or enough_convert is enough_convert version.

Wait, what is this about?

Dylan (not associated with this project in any way) explains the world of text encoding quite well: Plain text? Really?

It's 2022, do we still need this?

Short answer: yes.

Long answer: yes, there are still many web pages, emails and other content out there that is encoded in various text encodings.
