Hi, and thanks for the replies.
I kinda guessed this would be the case, but I posted anyway in the forlorn hope you guys might have a simple workaround.
What you suggest would, of course, work but this is for general distribution and, as far as I know, Epub3 is still a bit of a way off for general usage.
Doitsu: using SVG images may prove to be the most elegant way, under the circumstances (i.e. Epub2), however, there are approximately 270+ Chinese words containing many different individual characters and I'm not that familiar with Illustrator. Also, I doubt it could be done quickly.
I may just suggest they only offer the Kindle version, since it's widely available on Android devices. Perhaps they could offer the epub, and put a disclaimer on it saying the Chinese characters will not display correctly.
I think I just stepped off the boardwalk on our little wild west town called Ebooks and got my feet muddy

Thanks again,
John.
