I suggest to reconsider the information “always”.

Such an expectation can be fine if alternatives would be specified in
the notation “(?:…)”.

I hope this also when such a specification is actually needed.

I propose to reconsider also this view.
How should titles be safely handled if they contain the mentioned
quotation characters?

Can it be that you are used to the application of a specific language
where you should choose between two quotes for specification
of attributes (or text)?
