Adobe PDF Responding or Freezing PDFSHXTEXT

So i have a file (blueprint) that keeo freezing because the fonts are PDFSHXTEXT ( File created in Autocad)

This stops me from editing the file , as soon as i edit Adobe is " reconising the font" then most of the font changes to something else . the PDFSHXTEXT is the font. can i add it so Adobe Pro DC can handle it. as this causes me to restart the program everytime.
