Resolving this as a duplicate of all the related and  more specific issues filed by Ken. 
It looks like after applying all his patches we've pretty much covered the use case expressed

> Charset hint in metadata
> ------------------------
>                 Key: TIKA-344
>                 URL: https://issues.apache.org/jira/browse/TIKA-344
>             Project: Tika
>          Issue Type: Improvement
>          Components: parser
>    Affects Versions: 0.6
>            Reporter: Piotr B.
>            Priority: Minor
> It would be nice if TextParser and HtmlParser support Metadata.CONTENT_ENCODING hint.
> In my application I always prefer that hint (if it is present) over the charset detector
result, because charset detector is often wrong on short inputs (even if  match.confidence
is 100) and I know that hint if present is right in 99%.
> To be more general, user might be able to change default behaviour by override a function
 F(hint, detectorResults) -> charset. 
> Other solution is to create some standard strategies and let user to choose one of them:
> a) hint is most important
> b) charset detector result is most important
> c) create some heuristic using detectorResult.confidence, hint and maybe input length
> Maybe the last heuristic method would be good enough for most cases.
