How to update?
Although Uniscribe has been available since Windows 2000, new versions of Uniscribe provided more functions to the system, namely, support to other writing systems. An earlier update of it supports the display of Arabic and Hebrew, then Thai and Vietnamese. Since Windows XP, more South Asian and Assyrian alphabets are supported.If a user needs to use the newer usp10.dll for only certain applications, they are permitted to copy the newer version into the executable directories of those applications. However, newer versions of usp10.dll are not allowed to be re-distributed according to Microsoft's licensing agreement. Therefore, they are always encouraged to join the Microsoft VOLT discussion forum in order to get the latest version of usp10.dll. This is considered to be troublesome by most novice computer users, who need to type text in certain unsupported writing systems but are stuck with older versions of usp10.dll.
