Tibetan Editing on Windows Computers
From Digital Tibetan
Tibetan Unicode enabling Windows Vista
Input methods and complex script display
No software needs to be installed: Windows Vista already contains all three required components: an input method (see Control Panel / Regional and Language settings for a Tibetan keyboard), support to display Tibetan script and a Tibetan font, Microsoft Himalaya.
Tibetan Fonts
In addition you might want to install additional Tibetan Fonts (all existing Unicode fonts seem to work well) or an alternative Tibetan Input Method, for example TISE.
You can directly start using Notepad, OpenOffice or the latest Microsoft Office version to create Tibetan documents in standard Unicode encoding.
