I have written a shell script that

1) reads the comment tag from an MP3 file with ExifTool
2) converts the MP3 to a different format with ffmpeg
3) writes back the comment to the new mp3 with eyeD3 with the line

Code: Select all

/usr/local/bin/eyed3 --encoding utf8 --v2 --comment "$sMP3TagComment" "$sOriginalDateiname"

This works perfectly when running it in Terminal or in CodeRunner.

However, when using it as an external script in a Hazel rule and applying it to the same MP3 file, the "eyeD3" command line fails with the error

Code: Select all

eyeD3: error: argument -c/--comment: invalid UnicodeArg value: 'eyeD3: error: argument -c/--comment: invalid UnicodeArg value: '1. Unerm\xc3\xbcdlich, engagiert und streitbar - Bischof Erwin Kr\xc3\xa4utler im Gespr\xc3\xa4ch.'

I am puzzled why running the script through Hazel would seem to influence string encoding?

I'm not sure but keep in mind that when run in Hazel, your environment is different. Maybe eyeD3 requires some env var to be set.

Thank you for pointing this out.

I had assumed that the default character encoding for every shell environment is UTF-8, but obviously not.

After adding

Code: Select all

LC_CTYPE=UTF-8
export LC_CTYPE


as the first statements of my script, it now also works correctly in Hazel.
