Tibetan Input in Leopard - MacOSX 10.5

If you enable those, you will get new input methods. Those could be enabled/disabled at the small icon next to the volume icon in the top-right corner.
What this all means that it's now very, very easy to type Unicode Tibetan on a Mac system! I have not tried out the Sanskrit level stacking which is usually tricky, as Wylie does not really cover it all, but general Tibetan works just fine, and the new built-in font also looks very nice. The default size is usually small, so you need to adjust this if you type documents and entries with Tibetan fonts.
