[teiid-issues] [JBoss JIRA] (TEIID-4220) Unsupported encoding when POSTing to odata on Windows

From what I can glean an exception is expected or at least allowed behavior. Since cp1252 is not a standard charset name http://www.iana.org/assignments/character-sets/character-sets.xhtml - it is not required for the parser to recognize it. Woodstox attempts to change it into an IBM name, Xerces requires a feature setting https://xerces.apache.org/xerces2-j/features.html to allow Java charset names to be used, and fasterxml allows Java charset names by default. So the behavior will vary depending upon which library is used.
