emacs术语模式下的Unicode字符 [英] Unicode characters in emacs term-mode

问题描述

我在正常的终端会话中使用ansi-term。我倾向于在我的提示符中使用unicode字符来做基于我正在使用的源代码控件类型设置尾随字符的事情。

我使用字符± 作为我的git存储库提示。

在Emacs的安全术语中，我的提示没有呈现为unicode，并显示为\302\261 。显示当前编码系统显示，默认为输入到进程的utf-8-unix，但是我将原始二进制文件作为解码输出。我可以打C-c RET p改变编码和解码编码系统。当我启动一个终端时，我正在绘制一个如何自动设置的空白？我已经尝试添加到term-mode-hook来设置缓冲区的编码系统无效。我想我已经在term.el中找到了我正在寻找的内容，但是我并不在乎调整分发elisp，而且似乎添加了原始的二进制文件来修复其他地方的错误。

编辑：原来不清楚。我在MacOS上设置可可式Emacs 23.3下安装程序的默认流程编码系统的问题。 Emacs本身没有运行在终端中，我的终端正在Emacs中运行。

解决方案

在更好地了解 term.el ，以下作品：

 （defadvice ansi-term（之后adv-ansi-term-coding-system）
（set-buffer-process-coding-system'utf-8-unix'utf-8-unix））
（ad-activate'ansi-term ）
  

尝试使用 term-mode-hook 因为在term.el中， term-mode-hook 在切换到终端缓冲区之前被调用，所以 set-buffer-process-coding -system 由于缺少与缓冲区关联的进程而中断。

I use ansi-term for my normal terminal sessions. I tend to use unicode characters in my prompt to do things like set the trailing character based on the type of source control I'm using.

I use the character "±" as my prompt for git repositories.

In Emacs' ansi-term, my prompt isn't rendered as unicode, and shows as "\302\261". Displaying the current coding system shows that it defaults to utf-8-unix for input to the process, but I get raw binary as the decoding output. I can hit C-c RET p to change the encoding and decoding coding systems. I'm drawing a blank as to how to set this automatically when I start a terminal? I've tried adding to term-mode-hook to set the buffer's coding system to no avail. I think I've found what I'm looking for in term.el, but I don't care to tweak the distribution elisp, and it appears the raw binary was added to fix a bug somewhere else.

EDIT: This was unclear originally. I'm having issues setting the default process coding system for ansi-term running under Cocoa-ized Emacs 23.3 on MacOS. Emacs itself isn't running in a terminal, my terminal is running in Emacs.

解决方案

After getting a better understanding of term.el, the following works:

(defadvice ansi-term (after advise-ansi-term-coding-system)
    (set-buffer-process-coding-system 'utf-8-unix 'utf-8-unix))
(ad-activate 'ansi-term)

Trying this with term-mode-hook is broken because in term.el, term-mode-hook is called before switching to the terminal buffer, so set-buffer-process-coding-system breaks due to the lack of a process associated with the buffer.
