Well it is correctly implemented, it is meant to read bytes to String using the passed encoding and not for conversion.

Yes, that is why most applications do not try to guess the encoding themselves. Guessing/Intelligently identifying the encoding could pose problems, for e.g.,

"The user application may be expecting only the specified encoding, whereas due to intelligent scanning we might read all encoded streams"

Will this lead to Security issue? I do not know ATM.

I would do this. A setting in the SOAPProxy action like this would be sufficient for downloading and converting the file.

<action name="proxy" ..>
    <property name="wsdl-encoding" value="ISO-8859-1" />
</action>


But the major setback is this[1] as the BasicProfile mandates the WSDL and SOAP be only UTF-8 or UTF-16.

One more thing is that the attached ItemService.wsdl is actually "ISO-8859-1" encoded file, but just has been specified as "UTF-8":

This type of WSDL should not be allowed according to BP!
