For feature requests or enhancements, provide this information, please:

Which use case/requirement will be addressed by the proposed feature?

For VARCHAR columns they should always be strings regardless of collate/charset as mentioned in the docs.

Implementation ideas (optional)

For collations that end in _bin the Vitess type is VARBINARY so we need some additional handling to distinguish between actual VARBINARY and VARCHAR with binary collations.
