Hi Myles,
             Do you use UTF-16 encoding with Synapse-1.2 or have you used UTF-16 to prove your point?

> The following code exists in the org.apache.synapse.transport.nhttp.ClientWorker class' run() method:
>                 responseMsgCtx.setProperty(
>                     Constants.Configuration.CHARACTER_SET_ENCODING,
>                     contentType.indexOf(HTTP.CHARSET_PARAM) > 0 ?
>                         charSetEnc : MessageContext.DEFAULT_CHAR_SET_ENCODING);
> This fails however for the following Content-Type HTTP header:
>   application/soap+xml; action="urn:echoResponse";charset=UTF-16
> BuilderUtil.getCharSetEncoding(contentType) is called a few lines up and correctly extracts the UTF-16 character set value, but then overrides this and sets it to UTF-8. It does this because the value of org.apache.http.protocol.HTTP.CHARSET_PARAM is "; charset=". That is, it's failing because the response does not have a space between the charset parameter and the previous parameter.
> Reading through the HTTP specs, I haven't come across anything that says either that whitespace is permissible or not permissible here. In my view the code should therfore be flexible enough to handle either case. 
> I would suggest simpifying the code to:
>      responseMsgCtx.setProperty(Constants.Configuration.CHARACTER_SET_ENCODING, charSetEnc);
> as the BuilderUtil.getCharSetEncoding() code above the offending code seems to be sufficient at first glance.
