In the attached images (original and preprocessed before OCR), I have some 
lines of text which include the following:


   S/A  2/2
   Map  G/1

Using tesseract 3.02 (under the covers of MATLAB R2017b), when this image 
is analyzed as a block, I get inconsistent recognition of the slashes:

   SIA 2/2
   Map GI1

I find it interesting that the first slash in S/A is interpreted 
differently from the slash in 2/2. 

Any suggestions for how to get the slashes to be recognized correctly 

Thank you.
