Comment 13 for bug 1824260

The proposed patch might not fix the problem on all machines because not all monospace fonts have the same metrics as Courier. So it would be good to also add the following to 30-metric-aliases.conf:

   <alias binding="same">
     <family>CourierStd</family>
     <accept>
       <family>Nimbus Mono PS</family>
       <family>TeX Gyre Cursor</family>
       <family>Cousine</family>
       <family>Liberation Mono</family>
       <family>Cumberland</family>
       <family>Cumberland AMT</family>
     </accept>
   </alias>
