How do I get my Japanese VLC song title, out from inside a zip?

I initally had this problem: How to unzip a Japanese ZIP file, and avoid mojibake/garbled characters

But that "unzip -O shift-jis [filename.zip]" did the job and I got my nice Japanese characters in the file names, but that didn't seem to work for the file metadata?

I found this: Why does my VLC window show weird fonts?, but its solution seems to be for subtitles only, and my issue doesn't seem to be a VLC thing, since the audio file's Audio properties says that its title is, showing as mojibake blocks on my screen but when copy-pasted here, they turn into characters that take up no space: "Ôç©d¸UE - C[h"

Also, my Neptunia Re;Birth1 music is lining up with the reports of everyone else: Tracks 1 and 18 are Japanese, the rest seem to be Mojibake.

I guess if I just wanted to figure out the names, I do something like: the answers for How to turn mojibake text to readable form?

First step: determine what encode the metadata is written?

Install Exif reader

sudo apt install libimage-exiftool-perl

Show exif information you want to play on VLC.

exiftool filename

Sample output:

If you can read exif metadata normally in your terminal, then the metadata is written in Unicode. (check echo $LANG) And also check the VLC font settings.

Otherwise, it is written in another character encode. In Japanese, it probably is in Shift-JIS or EUC.

Now save text of exiftool exiftool filename > textfile.txt

Encode Shift-JIS (or EUC-JP 'eucjp') to Unicode UTF-8

iconv -f sjis -t utf8 textfile.txt

cat textfile.txt

If you see this file No Tofu characters then you can edit original exif with them.

For example: exiftool -Title="グラスホッパー" -Artist="スピッツ" -Album="ハチミツ" Let's play this song/video on VLC, see what is changed.
