branch: master
commit 4610241a9b3fbddd1f0973bf49f7008ed09ab955
Author: Basil L. Contovounesios <contovob@tcd.ie>
Commit: Basil L. Contovounesios <contovob@tcd.ie>

    Fix coding system in eww-display-pdf
    
    * lisp/net/eww.el (eww-display-pdf): Make *eww pdf* buffer unibyte
    before populating it to avoid conversions.  The binding for
    coding-system-for-write is then no longer necessary, and can be
    delegated to the viewer invoked by mailcap-view-mime.  Suggested by
    Stefan Monnier <monnier@iro.umontreal.ca>.  (Bug#44338)
