Get your Image converted to text at text-image.com. All the imges encoding are read to its best and at the end the according to the encoding the characters are repalced. check out the character version of yourself.
Being a programmer, I know the pain if I want to get the text from an Image to a notepad. Sometimes it is impossible!!! But there are other work arounds like, changing the image to TIFF or other format, then to a PDF, then to a searchable PDF, and then to a text file. Otherwise you can choose to read the whole encoding in the image, remove the compressions, analyse bit by bit and do it. I donn knwo if there is possible simpler way to achieve the same.
