Web Browsers: Currently only Internet Explorer 8 supports tb-lr (displaying vertically from left to right). Internet Explorer 6 & 7 support displaying vertically, but only tb-rl can be used. None of the other web browsers support displaying vertically.
There are less than 200 letters and symbols for Mongolic Languages (Manchu, Sibe, Daur, Traditional Mongolian, Todo Mongolian, Traditional Mongolian Ali Gali, Todo Mongolian Ali Gali, and Manchu Ali Gali). But the words need to be written vertically and all letters are connected and converted to a specific form in a word. So when we create a Unicode standard font, we will create OLT for the font, too.
We have created fonts for Manchu, Sibe and Daur. And we will create a font for all Mongolic Languages later.
Generally speaking, we will created a font for Manchu, Sibe and Daur first (we will name it as Daicing X). Then we will create one for all Mongolic Languages (we will name it as Daicing X the Full).
