I'm now fairly sure that the source encoding is the problem. I saved the source of the index page and of the first two links followed, then converted these Windows-874 files to UTF-8, edited INDEX in the recipe to point to the local UTF-8 converted copy, and edited the links in the index page to point to the local UTF-8 converted copies for the two links copied.
I've attached the epub and mobi versions of the e-book built for you to check. The text now looks Thai to me!
