Known weaknesses

- 01
Limited language support
Filenamify is primarily developed for JavaScript, which limits its utility in projects using other languages.
- 02
Narrow scope of functionality
The tool only focuses on converting strings to filename-safe formats and does not provide additional file management or manipulation features.
- 03
Potential for inconsistent behavior across filesystems
Different filesystems have varying rules about valid filenames, and Filenamify may not cover all edge cases universally.
