Git search commit with specific unicode char in content

I want to get all commits with a specific unicode char (https://www.compart.com/fr/unicode/U+200B) : Zero Width Space (U+200B).

git log -G 'regex'

This command should give me all commits with content that match the regex (Git Doc).

I want to catch Zero Width Space but the following command returns me an empty list :

git ls -G '\u200b'

But, I have some commits with this type of character. git diff gives me :

-       path(r'v1/status<U+200B>/<str:key>', views.status, name="status<U+200B>"),

What's the way to search for unicode char in commits ?

unicode git regex

I could only get it to work with the help of ANSI C quoting, i.e. $'\u200b':

zb@db:/tmp$ mkdir so70109544
zb@db:/tmp$ cd so70109544/
zb@db:/tmp/so70109544$ git init
