Problem

-- B2Bi sends an IDOC message to SAP using an Application Delivery type ALE

-- the message contains chinese characters

-- the encoding set at the Application Delivery level is "unicode"

-- the encoding set in SAP client is "unicode"

-- the output message exported from Message is correct and the chinese characters are correctly displayed

-- but the chinese characters are not correctly displayed in the SAP client (the encoding is wrong)

Resolution

* set also the encoding in Integrator/local/config/java/jvm.cfg:
WINDOWS:Append= -Dfile.encoding=UTF-8
