Two slashes are needed because \ is used to start an "escape sequence". Escape sequences include "\n" for newline, "\t" for tab, "/b" for backspace, "\\" for a single back-slash, etc. "\M" is an UNKNOWN string escape, as in the error message. See tutorial/InputSyntax in the Documentation center. There are also escape sequences such as \[Alpha], which is the greek letter alpha (with or without quotes).
