The main problem I was having is that certain fields in the admin area aren't able to be changed on a per-language basis, which makes certain symbols go weird at times.

I've set up a test store at http://www.phreakymonkey.com/unicodetest/

Under the featured products, I've modified the product 'Rope', so it has Japanese and English characters and symbols for both languages. You'll also notice the yen symbols in the currency dropdown menus and in the price, with both the ¥ on the left and the kanji on the right (goofy looking, but there for demonstration purposes). Here's a screenshot of what it should look like. Post if your browser displays it differently. If you don't have Japanese languages installed, Japanese characters will probably be displayed as question marks.



I'll send you an admin password so you can poke around, Crystal.
