Error Message :

PREP_PROCESS_REPORT returns an empty string when searching for umlauts using lowercase letters.  This is independent of the database (Oracle or MSSQL) or the Agent type (Unix or Windows).  
If the same search is performed in uppercase, the system works as expected.
 
Example:
 
Lowercase umlauts return the following in the report:
