The default language of an OCR engine is English. This can be changed for any of the built-in engines by accessing the Properties panel and adding the name of the language between quotation marks, as seen in the screenshots below:

📘

Note:

For the Google OCR engine, the Language field needs to contain the language file prefix, such as “ron” for Romanian, “ita” for Italian, "jpn" for Japanese, and “fra” for French.

📘

Note:

ABBYY FineReader Engine includes the majority of supported OCR languages by default. They can be used right after a successful installation of the engine.

The language for the Microsoft OCR engine can also be changed in a Screen Scraping activity when selecting “OCR” as the Scraping Method.

This can also be done for the Google OCR engine.

📘

Note:

ABBYY OCR is not available in the default Screen Scraping window. You can change the language of the OCR engine by modifying the Language property.
