the file will be saved silently with the appropriate coding.
Previously you would be prompted for a safe coding system.
+** New variable `inhibit-iso-eacape-detection' determines if the
+coding system detector pays attention to ISO2022's escape sequences.
+If this variable is non-nil, the detector ignores such escape
+sequences. The default value is nil, and it is not recommended to
+change it except for such a special case that you always want to read
+any escape code verbatimly. If you just want to read a specific file
+without decoding escape codes, use C-x RET c
+(`universal-coding-system-argument').

** Variable `default-korean-keyboard' is initialized properly from the
environment variable `HANGUL_KEYBOARD_TYPE'.
