history

Project history and usage

MP3Unicode is a small command-line utility by Andrei Dubovik and Alon Bar-Lev for converting MP3 ID3 tag text between character encodings. Its project page and man page describe the core workflow: read ID3v2, or ID3v1 when ID3v2 is absent, interpret text fields with a chosen source encoding such as cp1251, and write the result back as Unicode ID3v2 while optionally stripping ID3v1.

How it is used

The tool belongs to the class of audio-library repair utilities that exist because older MP3 collections often contain tags written in local 8-bit encodings. Its practical use is batch cleanup: users select a source encoding, choose whether ID3v1 and ID3v2 tags should be written, removed, or preserved, and can preview changes before modifying files. The 1.2.1 release noted fixes around command-line behavior and save-failure reporting, matching its role as a narrow Unix-style fixer rather than a general tag editor.
