Illion AU Credit Enquiry; better handling of non-ASCII characters

The Illion AU Credit Enquiry does not handle diacritical or other non-ASCII characters, sometimes returning the server error "An exception occurred while processing the request (50)".

finPOWER Connect now updates diacritical characters to their Latin alphabet base letter, e.g. "Á" is sent as "A".

Non-Latin characters, such as Chinese characters, will fail validation with the message "Invalid {Field Name}. One or more characters are not supported by the service provider."
