Read scanned pdf with ocr having different regional languages of India

We have some scanned pdf having data in different regional languages which are supported by Tesseract ocr, but when we use Read pdf with ocr (Tessaract), it shows strange output in message box, Is this due to font? , But then this text has to be converted into English. How the output from ocr can be taken out.
This ocr is giving good result for English. But the problem is for other languages like Hindi, Malayalam, Bengali, urgu, Marathi, Tamil, Telugu, Punjabi etc.
