Language settings

If the text you are sending as mobi/epub is in a language other than English is there any way to change the embedded language settings to that language?

We do this automatically for some languages (we try to detect the language), but there are some languages which, in the past, wouldn’t work with Amazon’s Kindle ebook creator tool. So in those cases, even if we detected the language, it would still be set to English. When we start using the new version of their tool, we’ll be able to support a wider range of languages.
