I was hoping to avoid using an embedded font, as it increases the size of the Kindle file. However, after tearing my hair out trying all the suggestions here and elsewhere without success, I've embedded an open-source font called Gentium that contains the full complement of Unicode characters, and that has resolved the problem.

It appears there are some Unicode characters that simply aren't present in the font that Kindle for Windows uses, and there's no way around that other than using a different font.

Thanks!
