编辑。在emacs中，我运行了Alt + X eval-buffer命令。我的操作系统是windows。当我重新启动emacs时，它显示以下警告:
警告(初始化):加载时发生错误"…/.emacs.el":
错误:Unicode转义使用非十六进制数字
为确保正常操作，应检查并移除初始化文件错误的原因。启动Emacs'——debug-init'选项查看完整的错误回溯。
. emacs。厄尔是:

我该如何解决?
问题出在这几行:
(setq backup-directory-alist
`((".*" . ,"D:Unix-Tmp")))
(setq auto-save-file-name-transforms
`((".*" ,"D:Unix-Tmp" t)))
U引入unicode转义…后面必须跟着十六进制数字。
你实际想要的是一个反斜杠字符，所以你需要转义它;例如
(setq backup-directory-alist
`((".*" . ,"D:\Unix-Tmp")))
(setq auto-save-file-name-transforms
`((".*" ,"D:\Unix-Tmp" t)))
参考:http://www.gnu.org/software/emacs/manual/html_node/elisp/Basic-Char-Syntax.html Basic-Char-Syntax
然而，这似乎导致另一个问题。更好的解决办法是按照@Stefan的建议去做。使用"/"而不是""作为路径名分隔符。(它应该在Windows上也能工作…)
错误由D:Unix-Tmp引起，U引入unicode转义，如Stephen所说。
但是当我改成:
(setq backup-directory-alist
`((".*" . ,"D:\Unix-Tmp")))
(setq auto-save-file-name-transforms
`((".*" ,"D:\Unix-Tmp" t)))
会抛出另一个:
加载d:/git_root_tfs/工作站/unix主/.recentf……做清洁在最近的名单上…关于GNU Emacs的信息GNU系统，输入C-h C-a。make-auto-save-file-name:无效在替换文本
中使用' '
最后我把路径改为D:Tmp-Unix，它工作了。
(setq backup-directory-alist
`((".*" . ,"D:Tmp-Unix")))
(setq auto-save-file-name-transforms
`((".*" ,"D:Tmp-Unix" t)))

始终使用正向斜杠而不是反向斜杠作为Emacs中的文件名。Windows通常更喜欢反斜杠，但除了少数例外，Windows实际上也接受正斜杠。
Windows中的Emacs将正斜杠(/)视为反斜杠()。当指定任何类型的路径时，应该始终使用正斜杠。Emacs将正确地解释它们。这允许您控制转义序列的使用次数，以达到预期的效果。
C:/Users/username/AppData/Roaming/.emacs是Emacs中完全有效的路径/文件名。
