# [soap ui][wsdl] org.apache.xmlbeans.XmlException: java.io.CharConversionException: Malformed UTF-8 character

This error is almost always the case when you have a windows (cp-1254) system and working with linux systems, which by default is utf-8.

In this case if the wsdl have a special character that windows don’t reconize, lauch the error above.

To solve the problem just change the parameters of the JVM that Soap UI use.
