emacs 文本模式 UTF-8 字符

emacs 文本模式 UTF-8 字符

我无法让 emacs（版本 24.4.1）在文本模式（-nw启动选项）下直接显示 Unicode 字符。它以转义形式输出它们，例如ä变为\344。当我保存文件时，它被编码为ISO-8859，即使我的系统区域设置是en_US.UTF-8.

终端本身可以显示Unicode字符外部emacs 的；例如，在 bash 中，ä变成ä.它也适用于 emacs X 应用程序（不带-nw）。

我正在 Arch Linux 3.19.3-3 上使用 gnome-shell 3.16.0-2运行xterm -u8（使用相同的结果）。uxterm

localectl输出：

   System Locale: LANG=en_US.UTF-8
       VC Keymap: sv-latin1
      X11 Layout: se
       X11 Model: pc104

locale输出：

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

由于唯一的问题区域是终端模式下的 emacs，我猜这就是问题所在。有任何想法吗？

更新：

~/.emacs:

(prefer-coding-system       'utf-8)
(set-default-coding-systems 'utf-8)
(set-terminal-coding-system 'utf-8)
(set-keyboard-coding-system 'utf-8)

(setq x-select-request-type '(UTF8_STRING COMPOUND_TEXT TEXT STRING))
(custom-set-variables
 ;; custom-set-variables was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.

   ["#2d3743" "#ff4242" "#74af68" "#dbdb95" "#34cae2" "#008b8b" "#00ede1" "#e1e1e0"])
 '(current-language-environment "UTF-8")
 '(custom-enabled-themes (quote (manoj-dark)))
 '(font-use-system-font t)
 '(inhibit-startup-screen t)
 '(tool-bar-mode nil))
(custom-set-faces

 )

我尝试注释掉文件中的每一行，但之后的结果是一样的。

经过一番摆弄，我发现它与系统相关，而不是与 emacs 相关。显然我的区域设置不知何故搞砸了，正如我们在OP中看到的：

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

我做了什么来解决它：

在 中/etc/locale.gen，取消注释/添加表示 的行en_US.UTF-8 UTF-8。确保它是唯一未注释的行。UTF-8如果您想使用其中之一，它应该可以与任何其他设置一起使用。暴力方法是：

$ sudo bash -c 'echo en_US.UTF-8 UTF-8 > /etc/locale.gen'

之后，我们生成区域设置并将其存储在系统配置中：

$ sudo locale-gen
$ sudo bash -c 'locale > /etc/locale.conf'

您也许可以在不重新启动的情况下更新设置，但我没有找到方法。
