I have a question though. I was aware of the set-buffer-file-coding-system command; when I tried it I was prompted with utf-8[1] which did not seem to do anything. What confuses me is this prompt along with separate markers on the modeline for charset and line ending style[2] led me to believe the coding system of the file is the charset (as in the characters used in the text) it is using, whereas line endings are set by something else. From your answer it seems that is not the case. Does that mean there can be several coding system associated to a buffer? Am I talking gibberish or does my question make any sense? Thanks, Footnotes: [1] I use utf-8 for all text files. [2] There is a U for files with UTF-8 characters and DOS for files with DOS style line endings at separate places on the bottom left of the modeline. -- Suvayu Open source is the future.

At C-x C-m f prompt, you can choose utf-8-unix, utf-8-dos, utf-8-mac apart from other options that start with utf-8. The two things - encoding and what constitues a eol character - are orthogonal to each other.

With TAB Emacs show possible completions. Also I recommend such settings: (require 'icomplete) ; Interactive completion in minibuffer. (icomplete-mode 1) So when you type utf-8 it show you: utf-8{-dos,-mac,auto,....} -- Best regards! ^ permalink raw reply [flat|nested] 8+ messages in thread

No, the coding-system includes both the character encoding and the EOL encoding. See the node "Coding Systems" in the Emacs User Manual. > >From your answer it seems that is not the case.
