I thought that was obvious: because it supports all the characters Emacs can handle. > In the thread, you objected to utf-8 because Emacs-mule supports some > characters that utf-8 doesn't (I hadn't known that, but I'll take your > word for it). In Emacs 22, only mule-unicode-* characters can be encoded with UTF-8. We do a lot of juggling behind the scenes to pretend that characters from other charsets are somehow equivalent to (or mapped into) Unicode codepoints, but that's camouflage. Cyrillic ISO-8859-5 characters and Cyrillic mule-unicode-* characters are still different characters, for example. > However, Juanma pointed out that utf-8 was used for the > ido-history file, and that the reason this was okay was that the data > is just filenames (as with saveplace); he pointed to a thread on this. That discussion was about Emacs 23, which will be Unicode based and where UTF-8 will be able to support all characters (or so I think). EMACS_22_BASE is a stable branch, so we are not supposed to install there changes that _might_ work, only changes we know _for_sure_ they _will_ work.
