Retrieving security question fields with op read

We're trying to use 1Password's support for security questions, but having difficulty retrieving the values for fields that have a question mark at the end. For example,

op read "op://MyOnePassword/SomeAccount/What is the street name on which you grew up?"

yields a "could not parse query parameters" error. Encoding the question mark at the end as %3F doesn't help. What's the correct syntax for retrieving fields like this?
