Panic writing a Dictionary(_, Utf8View) typed column to Parquet #10830
This is encountered when writing a Polars Categorical typed column to a Delta Lake table with delta-rs (see delta-io/delta-rs#3284). Polars uses a Dictionary(UInt32, Utf8View) for categorical columns, and attempting to write these columns to Parquet results in a panic: internal error: entered unreachable code: cannot downcast Utf8View dictionary value to byte array
