branch: emacs-26
commit 459b669b08d235a79ff4fa61b2d93e9a6229facd
Author: Eli Zaretskii <address@hidden>
Commit: Eli Zaretskii <address@hidden>
Fix failures of vc-find-revision with non-ASCII file names
* lisp/vc/vc.el (vc-find-revision): Instead of binding
coding-system-for-write, make the buffer-file-coding-system of
the temporary buffer be no-conversion. This avoids the
unwanted side effect of not encoding the command-line
arguments of the VCS commands invoked by the backend.
(Bug#34350)
