ACC2002: Like "String*" Criteria Is Incorrect on Indexed (Duplicates OK) Fields That Have DBCS Characters

When you use a LIKE clause on a column in a query, and the column has Double-Byte Character Set (DBCS) characters, not all the records that meet the criteria are returned.

All the records meeting the criteria may not be returned if the following conditions are true:

• The database consists of DBCS data, such as Korean or Chinese.
• The column is indexed.
• Alphanumeric characters are the leading characters in the string.
