FIX: Incorrect results when you use a LIKE operator and an "ss" wildcard in SQL Server 2014 or 2016

Symptoms
Assume that you run a query that uses a LIKE operator (pattern matching) together with "ss" as a wildcard character to find approximate matches. If the wildcard character is at the end of the statement, the result may not contain all the approximate matches.

Notes 
  • The LIKE operator supports both ASCII and Unicode pattern matching. This issue does not occur if the data is stored in Unicode data types.
  • This issue is known to occur in the German language, where the "ss" characters can be regarded as the same as the "ß" character.

Resolution
This problem was first fixed in the following cumulative update for SQL Server:
