Jonathan,
Good work on this.
The English pages are not giving an icon, although the code of the
translator is designed to scrape from either the English or the
Japanese interface. From a quick check and test, it looks like
changing "http:" to "https*:" in the "target" field of the translator
header will fix things. If you can make that change an re-up the
translator code, I'll click about a bit more to see if I can break
anything else.
