This is cool. I think the prior way to get Thai was a paid service. I hope they add this to the OS releases in the future as an option.

The only problem is it doesn't work with my favorite font - BBAlpha Sans in regular font style size 9. There's too much head space above the font so it pushes the text down and cuts of the bottom of the letters in lists like email subjects. It also doesn't work in size 7 or 8.

All the other fonts and BBAlpha Sans in bold or italic seem fine. Or in font size 10 and up.
