Do you mean "in some place where we store proj strings, they have
leading and trailing quotes"?    Or are you really invoking proj
command-line tools or libraries and passing the quotes?

Did you read the documentation, and is there a specification?

Removing all " seems like quite a leap and asking for trouble, when you
don't know, and you either haven't read the specification or there isn't
such a rule.  Remember that specifications control what happens in the
future without a breaking change announceent, so how it works today is
only part of the question.

Instead, I would add a rule on reading them that says if leading " and
trailing ", remove those two.

And then look at anything else with a " and think about it.  Please
report back with what you found as it may help others.
