Good question. The title is "Chinese-Barbarian Dictionary". Apparently it was first started under the Ming. Contrary to what I said earlier, different portions of it appear to be in different languages, including some in Persian and maybe Arabic as well. Jurchen too? This portion does not really look like Mongolian, but I don't know what Jurchen script looks like. It wouldn't surprise me if it was.
In any case, it doesn't include any Burmese, at least not in the section on the Internet Archive. I'd be interested to know what your interest is, Klend.
