The code changes in this commit add error handling to the `encode_ordinary()` method in the `CoreBPE` class. Previously, the method would raise an exception if an error occurred during the encoding process. With this change, the method now catches any exceptions and returns an empty list instead.

This commit addresses the need for robust error handling in the `encode_ordinary()` method, ensuring that the code gracefully handles any unexpected errors and prevents them from propagating further.
