Aspose.OCR for .NET can recognize a text in a large number of languages and all popular writing scripts, including texts with mixed languages.
To specify a language for recognition, provide one of the following values in Language property of recognition settings:
Mixed-language Cyrillic/English text recognition is experimental. If you are absolutely sure about the text language (for example, Ukrainian), it is recommended to specify the language directly.

If this parameter is omitted, the OCR engine will assume that the text is written in extended Latin.
Make sure you specify the correct language for the image. If you try to recognize Cyrillic text using
Aspose.OCR.Language.Eng, only the characters that look the same in both languages (for example, с and c) will be correctly recognized. Other characters will be replaced with similar-looking alternatives.
Example
The following code sample demonstrates how to specify the recognition language:
Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
// Add an image to OcrInput object
Aspose.OCR.OcrInput input = new Aspose.OCR.OcrInput(Aspose.OCR.InputType.SingleImage);
input.Add("source.png");
// Recognize Ukrainian text
Aspose.OCR.RecognitionSettings recognitionSettings = new Aspose.OCR.RecognitionSettings();
recognitionSettings.Language = Aspose.OCR.Language.Ukr;
// Recognize image
List<Aspose.OCR.RecognitionResult> results = recognitionEngine.Recognize(input, recognitionSettings);
foreach(Aspose.OCR.RecognitionResult result in results)
{
Console.WriteLine(result.RecognitionText);
}
