Owah Tagu Siam Nf Font

Not your garden-variety utility typeface but, if you need a faux Thai font, this is the one for you.

The upper and lowercase positions feature variant letterforms, so you can mix and match to create JUST the look you're after.

The commercial font is "new and improved" over the freeware version, with expanded character set and improved kerning, so you get what you pay (or don't pay) for.
