[Mattias Engdegård]

branch: master
commit 07a76a06f9a438e2a1bf1e565e3e78f7927c37f2
Author: Mattias Engdegård <mattiase@acm.org>
Commit: Mattias Engdegård <mattiase@acm.org>

    Fix test errors when run with fancy charset (bug#61534)
    
    * test/lisp/emacs-lisp/bytecomp-tests.el
    (bytecomp-tests--unescaped-char-literals, test-suppression):
    Bind `text-quoting-style` to `grave` around tests to force
    generation of ASCII quotes.
    * test/src/lread-tests.el (lread-tests--unescaped-char-literals):
    Subject the reference string to the same text styling as that
    under scrutiny.
