Symfony version(s) affected

6.49 and others

Description

Follow up of #57497 and #57612 and #57616

Behavior os snake() still contains a BC break.
I did not check whether this was introduced by the original change or one of the fixes.

For years the string123-customer,with/special#name was converted to 123-customer_with_special_name.
Now it returns 123-customer,with/special#name.

Many characters are not converted as before/expected.

How to reproduce

{{ '123-customer,with/special#name'|u.snake }}

shows 123-customer,with/special#name instead of the expected 123-customer_with_special_name

Possible Solution

Revert previous "fixes"?
