About:
Mp3unicode is a command-line utility designed to fix ID3 tag encoding issues in MP3 files.

This ensures proper display of song titles, artist names, and album information across different media players and operating systems.

Key Features:

Batch processes entire directories of MP3 files
Supports conversion between various character encodings
Preserves existing tag structure while updating encoding
Command-line interface for easy scripting and automation

Use Cases:

Fixing garbled text in MP3 file tags after transferring files between different operating systems
Standardizing a music library to UTF-8 encoding for consistent display in modern media players
