### Feature Request / Improvement Based on discussions from [iceberg-python/#584](https://github.com/apache/iceberg-python/issues/584), we found that the Java Iceberg library "sanitizes" and transforms column names with special characters before writing to parquet. For example, an Iceberg table with `TEST:A1B2.RAW.ABC-GG-1-A` column is transformed into `TEST_x3AA1B2_x2ERAW_x2EABC_x2DGG_x2D1_x2DA` which is then used to write the parquet files. This process is done for both reads and writes. The behavior was introduced in #601 I think Iceberg should (optionally) allow writing column names without the "sanitization" and transformation. This can be made configurable to enable backward compatibility. ### Query engine None -- This is an automated message from the Apache Git Service.
