   Glue is just trying to be generic, and the Athena doc requirement is based on Hive specification. I am trying to not remove this validation unless there is an absolute need. Using special characters cause a lot of incompatibility across different compute engines. Given the fact that people are likely going to create new namespaces for Iceberg tables, I think it's better to just advocate people to use normal characters instead of allowing too many variations.
   
   Please let me know what you think, or if you have some specific use case to satisfy.
