Uniscribe

From Wikipedia, the free encyclopedia

Uniscribe is the Microsoft Windows set of services for rendering Unicode-encoded text, especially complex text layout. They are implemented in the DLL USP10.DLL. USP10.dll became available to the public with Windows 2000 and Internet Explorer 5.0. In addition, the Windows CE platform has supported Uniscribe since version 5.0.

[edit] USP10.dll

USP is an acronym for Unicode Scripts Processor. The most recent version of usp10.dll available is 1.626.6001.18000. The main purpose of Uniscribe includes the following:

  1. arranging input text from the input sequence to visual sequence.
  2. substituting glyphs according to context (e.g. different forms of Arabic characters)
  3. ordering displayed text based on text flow direction (e.g. LTR vs RTL, Horizontal vs Vertical)

Here listed some common versions of usp10.dll, as well as the methods by which they are distributed:

[edit] How to update?

Although Uniscribe has been available since Windows 2000, new versions of Uniscribe provided more functions to the system, namely, support for 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 can copy the newer version into the executable directories of those applications.
