Can I use Lucene to index text in Chinese, Japanese, Korean, and other multi-byte character sets?

Yes, you can. Lucene is not limited to English, nor any other language. To index text properly, you need to use an Analyzer appropriate for the language of the text you are indexing. Lucene's default Analyzers work well for English. There are a number of other Analyzers in Lucene Sandbox, including those for Chinese, Japanese, and Korean.
