id3conv: a commandline tool to fix encoding error in music files

Currently, id3conv supports only conversion from GBK to UTF-8 assuming the ID3 tags were incorrectly encoded in latin-1 or ISO-8859-1 and decoded as UTF-8 on Unix-like systems.

requirements

• go >= 1.8
• dep >= 0.5

installation

1. clone this repo
2. dep ensure
3. cd main && go build
4. cp main where_you_wanna_be/id3conv
5. run it like id3conv ${musicFile1} ${musicFile2}
6. enjoy correct UTF-8 meta info in your music

integrate with macOS context menu with automator

1. open automator
2. create an empty service
3. set workflow receives current <- audio files in Finder
4. look for run shell script on the left menu and drag it in
5. input a script like this:

for f in "$@"
do
	/usr/local/bin/id3conv "$( echo "$f" | sed 's/ /\ /g' )"
done

Suppose you save your main binary as /usr/local/bin/id3conv.

1. save this service and you can use it in Finder
