Anders Lundberg commented on WW-3863:
-------------------------------------

Same reason as not using struts.i18n.encoding in WW-3059. A struts application supports any encoding, thanks to struts.i18n.encoding, but a json string, submitted and received by XMLHttpRequest, has to be UTF-8 encoded.
                
> Incorrect encoding in JsonResult

> org.apache.struts2.json.JSONResult uses the configured default encoding (in the struts properties, with the "struts.i18n.encoding" key) when setting the charset part in the response's content type.
> Shouldn't JSONResult.getEncoding() always return UTF-8, similar to the resolution of WW-3059?
> A simple workaround is to override JSONResult.getEncoding() and let it return UTF-8 but it would be preferrable if this was included in the distribution.
