* fix yaml to x150-series

* Fix: Prevent non-ASCII characters in YAML files (#2461)

This commit addresses the issue #2461 by updating the test case to detect non-ASCII characters in YAML files. The new check ensures that if any non-ASCII characters are found, the test will fail and provide a clear message listing the problematic characters.
	•	Added a check to identify non-ASCII characters in the content of the YAML files.
	•	If non-ASCII characters are found, the test will now fail with a detailed error message, including the list of non-ASCII characters.

This update helps ensure that YAML files are strictly ASCII-encoded, avoiding potential encoding issues in different environments.
