Isn't that a bug? When \240 occurs in a unibyte string, Emacs recognizes it as an eight-bit raw byte. When converting unibyte strings to multibyte, Emacs does not "unify" eight-bit raw bytes with Unicode characters #x80-#xff; they get their own code points, in this case #x3fffa0. (One reason for doing this is to allow unibyte strings to be specified using string constants in Emacs Lisp source code.) > How to use octal syntax to match that char? The Elisp manual says > clearly that "The most general read syntax for a character represents > the character code in either octal or hex." MOST GENERAL, not most > limited and partial. I've already edited the documentation to take out this sentence. It is incorrect anyway, for the reason that octal escapes are limited to three digits.
