Subject: Fix info-apropos when the default encoding is Latin-N
X-Git-Tag: emacs-25.0.90~1469
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=3d139d59fb0c3f4027109d4fac271a8aa52db5fc;p=emacs.git

Fix info-apropos when the default encoding is Latin-N

* lisp/info.el (Info-find-node-2): Reset the buffer's encoding to
'undecided', so that it is set to the encoding of the Info file we
are about to insert.  Otherwise, 'info-apropos' will fail to find
some index nodes in some UTF-8 encoded files, if the buffer's
previous encoding is Latin-N or some such.
