Remove the thin horizontal line

[Sundar Andaperumal]

Hi, 

 I am trying to remove the thin horizontal line; when doing so the text in the SUBTOTAL 

gets disturbed and gives special characters like this:  (`°`, `—`, `~`, `*`, etc.)

 How to ignore / remove this horizontal line and extract the proper text in the SUBTOTAL section. Image attached.

thanks!

The "mosquito noise" compression artifacts around all the sharp edges are going to make both line removal and OCR harder than it needs to be. If you can get image captures without that you'll have a much easier job.
