Scripts used by Urdu, Panjabi and Bengali are all supported in Unicode. Urdu can be written using naskh-style Arabic (supported on WinXP, Win2K...), but users strongly prefer nastaliq. The latter is supported by the Uniscribe shaping engine; MS has not yet shipped any nastaliq fonts, but some are available from other vendors.
Support for Gurmukhi script is included in Windows XP. Support for Bengali script will be available in WinXP SP2 (with a couple of minor issues that will get fixed in Longhorn or a subsequent XP service pack). Peter Constable
