The text cannot be extracted nor copy-pasted because it contains no back-translation info from the visible character images (glyphs) to Unicode.
This applies to all tool doing text extraction.
All you can try is OCRing the file.

is there any other solution, after all, the speed and accuracy of ocr are not as good as extraction

[JorjMcKie]

No, that's all you can do.
