SYMPTOMS

When you compare two Unicode strings by using the SQL_Latin1_General_Cp850_BIN collation, SQL Server is designed to compare the first character of each string, and then continue to perform a binary comparison of the remainder of the strings in a byte-by-byte manner. This can cause Unicode data to be sorted in a manner that you might not expect, if you are unfamiliar with these semantics.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.

MORE INFORMATION

This hotfix introduces a new collation, SQL_Latin1_General_Cp850_BIN2. The semantics of the new SQL_Latin1_General_Cp850_BIN2 collation compares the two strings character by character. The characters are compared by using the Unicode code point.

Code point is a numeric value in Unicode encoding, or in a code page that corresponds to a character. For example, in this new collation, character U-0140 is greater than U-0041, even though the in-memory representation of them is 0x4001 and 0x4100.
