Oleg Kalnichevski commented on HTTPCLIENT-1257:
-----------------------------------------------
One can force HttpClient to ignore malformed and unmappable characters using
"http.malformed.input.action" and "http.unmappable.input.action" parameters
http://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/params/CoreProtocolPNames.html#HTTP_MALFORMED_INPUT_ACTION
Header is an interface, so you can have a custom implementation of it backed by
a byte array instead of CharArrayBuffer used internally by HttpClient.

> The header has already been extracted in the wrong content encoding. I will

> I understand that this is not RFC normalised behavior, but the above url and
> redirect works fine in all browsers.
> Is it possible to access the raw header (byte array) so that I can chose the
> encoding on my own? This would help a lot. Or a parameter to optionally
> specify the encoding when fetching a header value.
