3118744 - Transformer exception occurs when executing XSLT with Japanese characters using MessageTransformBean in SAP PI/PO

In SAP PI/PO 7.50, an integration scenario is configured to use the MessageTransformBean in the Adapter Module configuration.

The integration processes files or payloads containing Japanese characters, and the character encoding appears to be configured correctly. However, during message processing, the transformation fails with an error similar to the following:

Mapping xxx failed to execute: MappingException: Mapping failed in runtime
Transformer exception occurred when executing XSLT FileAdapterHierarchyToProductCategoryHierarchyUpdated...

TransformException: Transformer exception occurred when executing XSLT FileAdapterHierarchyToProductCategoryHierarchyUpdated...

javax.xml.transform.TransformerException:

com.sun.org.apache.xml.internal.utils.WrappedRuntimeException:
