Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited support for non-European languages

   Accuracy drops significantly for less common or non-European languages, which may not meet the needs of all multilingual projects.

2. 02

   Performance issues with large datasets

   The library can be slow when processing a large volume of text strings, leading to increased computational time and resource usage.

3. 03

   Lack of active development and updates

   The last major update was several years ago, indicating potential stagnation in improvements and bug fixes.

4. 04

   Poor documentation for advanced features

   Detailed explanations of how to handle edge cases or customize the language detection process are sparse, making it difficult for developers to fully leverage the tool's capabilities.
