如何确定 OS X 中的文件编码? [英] How do I determine file encoding in OS X?

问题描述

我正在尝试将一些 UTF-8 字符输入到 TextMate (它说它的默认编码是 UTF-8)，但 LaTeX 似乎不理解它们.

I'm trying to enter some UTF-8 characters into a LaTeX file in TextMate (which says its default encoding is UTF-8), but LaTeX doesn't seem to understand them.

运行 cat my_file.tex 在终端中正确显示字符.运行 ls -al 显示了我以前从未见过的东西:文件列表中的@":

Running cat my_file.tex shows the characters properly in Terminal. Running ls -al shows something I've never seen before: an "@" by the file listing:

-rw-r--r--@  1 me      users      2021 Feb 11 18:05 my_file.tex

(而且，是的，我在 LaTeX 中使用 usepackage[utf8]{inputenc}.)

(And, yes, I'm using usepackage[utf8]{inputenc} in the LaTeX.)

我找到了 iconv，但这似乎无法告诉我编码是什么——它只会在我弄清楚后才会转换.

I've found iconv, but that doesn't seem to be able to tell me what the encoding is -- it'll only convert once I figure it out.

推荐答案

@ 表示该文件具有与其关联的扩展文件属性.您可以使用 getxattr() 函数查询它们.

The @ means that the file has extended file attributes associated with it. You can query them using the getxattr() function.

没有确定的方法来检测文件的编码.阅读这个答案，它解释了原因.

There's no definite way to detect the encoding of a file. Read this answer, it explains why.

有一个命令行工具 enca，可以尝试猜测编码.你可能想看看.

There's a command line tool, enca, that attempts to guess the encoding. You might want to check it out.
