Jukka Zitting commented on TIKA-209:
------------------------------------

I gave a look at the Nutch LanguageIdentifier code. It's indeed something we 
could use without too much effort.

> Language detection is weak.

> in org.apache.tika.utils.Utils the getUTF8Reader method assigns a language 
> determination without checking the confidence rating from ICU's 
> CharsetDetector.
> Please add a configurable level (0-100);
> if (language != null && match.getConfidence() > THRESHOLD) {
>   metadata.set(Metadata.CONTENT_LANGUAGE, match.getLanguage());
>   metadata.set(Metadata.LANGUAGE, match.getLanguage());
> }
> Obviously using charset to imply language is generally weak but it would be 
> sufficient if the confidence threshold was controlled. Today, the text 
> "hello" is tagged as French, for example.
