On a Windows Vista-based computer, you may notice that some right-to-left (bi-directional or “Bidi”) characters are displayed incorrectly when they are used with Left-to-Right Override (LRO) and POP Directional Format (PDF) control characters. Specifically, the “(” character (opening parenthesis) and the “)” character (closing parenthesis) are displayed in the reverse order of how they should be displayed.

For example, you have the following string:

LROA(B)CPDF

Note LRO and PDF represent the LRO and the PDF control characters, respectively. A, B, and C represent Bidi characters.

When you view this string example in an application in Windows Vista, such as Notepad, the Bidi characters are incorrectly displayed as follows:

A)B(C

However, when you view this string in Notepad in Windows XP or in Windows Server 2003, the Bidi characters are displayed correctly as follows:

A(B)C

Note This problem occurs in applications that use Uniscribe in Windows Vista.
