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
Module.Language.ENG, only the characters that look the same in both languages (for example, с and c) will be correctly recognized. Other characters may be misinterpreted as similar-looking alternatives or ignored completely.
Example
The following code sample demonstrates how to specify the recognition language:
// Prepare images
var source = Module.WasmAsposeOCRInput();
source.url = filename;
var content = new Module.WasmAsposeOCRInputs();
content.push_back(source);
// Set recognition language
var settings = Module.WasmAsposeOCRRecognitionSettings();
settings.language_alphabet = Module.Language.DEU;
// Recognize image
var result = Module.AsposeOCRRecognize(content, settings);
