OCR例子中，使用professional引擎，没有中文包，怎么处理？感谢！

OcrProfessionalRuntime

using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Professional, false))
         {
            // Start the engine using default parameters
            ocrEngine.Startup(null, null, null, @"D:\Program Files\LEADTOOLS 19\Bin\Common\OcrProfessionalRuntime");

            // Show languages supported by this engine
            string[] supportedLanguages = ocrEngine.LanguageManager.GetSupportedLanguages();

            Console.WriteLine("Supported languages:");
            foreach (string supportedLanguage in supportedLanguages)
            {
                  // Get the friendly name of this language using the .NET CultureInfo class
                  CultureInfo ci = new CultureInfo(supportedLanguage);
                  Console.WriteLine("  {0} ({1})", supportedLanguage, ci.EnglishName);
            }
