How to read $,~ etc special characters?

[kkul...@redhat.com]

I am trying to use tesseract in python to convert this image to string, but I am not able to get everything correctly in the output. The least I want it to recognize $ sign(in tmp_aNlkS.jpeg), and root@photon-machine [~]# (in tmpnQUDa8/jpeg) correctly. Currently it recognizes $ to be S or 3. and it does not recognize [~]# correctly in other case. 

Please guide.
