Hi,

I have built a gitbook with the bookdown package.

The search engine does work for English-written parts of the text and codes (i.e. alphabet and numbers, basically), but I have found that it doesn't work if I type in some Japanese words.

It would be wonderful if anyone could expand the search engine functionality so that we can look up for words written in multibyte characters.

I asked whether the feature is currently available on Stack Overflow, and Yihui kindly allowed me to post this feature request.

Thank you.
