You’re welcome, Nick.
This is not a bug. Double quotes take precedence over delimiters by design. This is exactly the reason they are needed in delimited data formats – to encapsulate strings that contain characters that are used as field delimiters.
I’d never encountered such cases previously. We will be adding a few advanced options to tweak parser behavior. Maybe we need to consider an option for disabling text qualifiers. At least, there is a relatively simple workaround for it.
