@vindex inhibit-iso-escape-detection
@cindex escape sequences in files
By default, the automatic detection of coding system is sensitive to
escape sequences. If Emacs sees a sequence of characters that begin
with an @key{ESC} character, and the sequence is valid as an ISO-2022
code, the code is determined as one of ISO-2022 encoding, and the file
is decoded by the corresponding coding system
(e.g. @code{iso-2022-7bit}).
However, there may be cases that you want to read escape sequences in
a file as is. In such a case, you can set th variable
@code{inhibit-iso-escape-detection} to non-@code{nil}. Then the code
detection will ignore any escape sequences, and so no file is detected
as being encoded in some of ISO-2022 encoding. The result is that all
escape sequences become visible in a buffer.
The default value of @code{inhibit-iso-escape-detection} is
@code{nil}, and it is strongly recommended not to change it. That's
because many Emacs Lisp source files that contain non-ASCII characters
are encoded in the coding system @code{iso-2022-7bit} in the Emacs
distribution, and they won't be decoded correctly when you visit those
files if you suppress the escape sequence detection.
