 ## Arguments  
  *character_expression*  
  Is an [expression](../../t-sql/language-elements/expressions-transact-sql.md) of character or binary data. *character_expression* can be a constant, variable, or column. *character_expression* can be of any data type, except **text** or **ntext**, that can be implicitly converted to **varchar** or **nvarchar**. Otherwise, use the [CAST](../../t-sql/functions/cast-and-convert-transact-sql.md) function to explicitly convert *character_expression*.  
+   
+> [!NOTE]  
+> If *string_expression* is of type **binary** or **varbinary**, RIGHT will perform an implicit conversion to **varchar**, and therefore will not preserve the binary input.  
   
  *integer_expression*  
  Is a positive integer that specifies how many characters of *character_expression* will be returned. If *integer_expression* is negative, an error is returned. If *integer_expression* is type **bigint** and contains a large value, *character_expression* must be of a large data type such as **varchar(max)**.
