Thanks a lot for the fix. Could you also create a corresponding issue for this PR to describe the problem?

I’d also like to better understand your use case: are you using your own Parquet reader in your environment? It seems the default Parquet reader would not return a dictionary for the binary type.

Also, there appear to be several places in the current codebase that forcibly assume a string dictionary, which may have similar issues. Would you prefer to address those in this PR as well, or leave them for follow-up PRs?
