I don't understand. "\alpha" is an ASCII string. Do you mean that x-symbol replaces the "\alpha" with α in the buffer, and allows you to try to save that? Uwe> According to Christoph in GNU emacs there is something like Uwe> "safe encoding" a feature which is missing here. Safe charsets prevents you from saving the buffer when charsets that are not savable in the current encoding are present. You can get a similar effect by enabling the latin-unity package, but it's limited (I think) to extended Latin characters. You could also set the buffer-file-coding-system to 'utf-8 (if you have Mule-UCS enabled) or to 'iso-2022-7. This will prevent corruption, but your files will not be readable by TeX. -- Institute of Policy and Planning Sciences http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
