Is it possible to automatically detect the language encoding of incoming data? For instance if Japanese is used, is there a way to know it is Japanese from a bit in the charset, a dictionary-based evaluation or otherwise?


Have a look at http://www.mozilla.org/projects/intl/chardet.html and http://chardet.feedparser.org/ for some implementations of this idea.

These detectors are often inaccurate though (and sometimes fail completely), see the warning at the bottom of http://chardet.feedparser.org/docs/supported-encodings.html
