      Description

      Currently, Tika uses icu4j for detecting charset encoding of HTML documents as well as the other naturally text documents. But the accuracy of encoding detector tools, including icu4j, in dealing with the HTML documents is meaningfully less than from which the other text documents. Hence, in our project I developed a library that works pretty well for HTML documents, which is available here: https://github.com/shabanali-faghani/IUST-HTMLCharDet

      Since Tika is widely used with and within some of other Apache stuffs such as Nutch, Lucene, Solr, etc. and these projects are strongly in connection with the HTML documents, it seems that having such an facility in Tika also will help them to become more accurate.
