Description
### Describe the bug, including details regarding any error messages, version, and platform.
I have a Parquet file with a column that contains a hyphen character and get the following error:
> Illegal character in: Creation-Time
I guess Parquet officially supports only alphanumeric plus underscore, but I have retrieved this Parquet file from a [blob inventory scan](https://docs.azure.cn/en-us/storage/blobs/blob-inventory-how-to) on Azure.
Might there be an option to allow such a column name in `parquet cat` for example?

Research direction
Start at the parquet cat CLI path and reproduce the failure with a Parquet file containing the Creation-Time column name. Trace where column names are validated, then determine how an opt-in allowance would affect the command. Done means parquet cat can process this column name without the Illegal character error while preserving existing validation behavior.
