X-Git-Tag: emacs-20.1~2224
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=f78da51e8dc0b1f8e7756e6b12954d79f1cd3d1c;p=emacs.git

(selection_data_to_lisp_data): If TYPE is `STRING'
and DATA contains 8-bit codes, decode them as Latin-1 characters.
(lisp_data_to_selection_data): Supply 4th arg TABLE as Qnil to
find_charset_in_str.
