Subject: Change the default value of gdb-mi-decode-strings to t (bug#44173)
X-Git-Tag: emacs-28.0.90~5225
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=1b9e159525409d6a1ad41686c34f66aa2effa71e;p=emacs.git

Change the default value of gdb-mi-decode-strings to t (bug#44173)

This is likely to be a more commonly wanted default value today.

* lisp/progmodes/gdb-mi.el (gdb-mi-decode-strings): Change default.
* doc/emacs/building.texi (Source Buffers): Update manual.
* etc/NEWS: Announce.

+  By default, source file names and non-ASCII strings in the program

+debugged uses a different character encoding, set the variable
+@code{gdb-mi-decode-strings} to the appropriate coding-system, or to
+@code{nil} to leave non-ASCII characters as undecoded octal escapes.

+This means that the default coding-system is now used to decode strings
