In Windows Vista, support was added for Oriya, Sinhala, Lao, Khmer, Mongolian, Tibetan, and Yi scripts. In Windows 7, support was added for New Tai Lue, Tai Le and Phags-pa scripts. (This is just focusing on Asian scripts.)

IE and .Net both rely on the same shaping implementation that is used in Uniscribe. There are some of the text stack elements, such as font fallback, that are different, but the shaping for complex scripts is the same. > But we have alternatives to Uniscribe on Windows.

I don't know of another implementation that supports as many scripts as are supported in Windows, but of course you can use alternatives, and I hope that, together with other implementations, the envelop will continue to be pushed out. > What are the projects for supporting more scripts in Windows 8 (or "Windows > Infinite" > if I just consider the logo I have seen), if it will be built with an > increased integration of > the browser (HTML5 and CSS 2 or 3) in its interface? More details about Windows 8 will be made available after the Build conference in September. But as noted above, IE / the HTML layout engine built into Windows uses the same shaping implementation. So, the additional scripts that are supported in Uniscribe will also be supported in IE, and also in DirectWrite and RichEdit. Peter
