True it this engine supports enabling multiple languages at the same time; otherwise it is false.
Some of the OCR engines supported by LEADTOOLS do not allow enabling more than one engine at a time. To check if the OCR engine supports more than one language, you must first check the value of the SupportsEnablingMultipleLanguages property. If the value of this property is false, then only the first item in the array passed to EnableLanguages will be used.
