Subject [jira] [Created] (CAMEL-10053) Bindy does not seem to support Cp922 character encoding

---------------------------------------

             Summary: Bindy does not seem to support Cp922 character encoding
                 Key: CAMEL-10053
                 URL: https://issues.apache.org/jira/browse/CAMEL-10053
             Project: Camel
          Issue Type: Bug
          Components: camel-bindy
    Affects Versions: 2.16.2
            Reporter: David Cornforth


If I use the {{charset}} option when consuming from a non UTF8 encoded file and then unmarshal
the result using a bindy object the result is either an exception or incorrect data.  Below
are some unit tests that illustrate the issue.  The UTF8 ones work, but all of the Cp922 ones
fail for a variety of reasons, both using {{BindyFixedLengthDataFormat}} and {{BindyCsvDataFormat}}.
 I have only tested this with Cp922, but it may be the case that other non-standard encodings
also exhibit the same behaviour.
