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

我正在尝试在 TextMate 中的LaTeX文件中输入一些UTF-8字符(表示其默认编码为UTF-8)，但LaTeX似乎无法理解它们.

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显示了我之前从未见过的东西:文件列表旁边的"@":

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

(是的，我正在LaTeX中使用\usepackage[utf8]{inputenc}.)

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

我已经找到了iconv，但这似乎无法告诉我编码是什么，只有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

@表示文件具有与之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.阅读此答案，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 ，它会尝试猜测编码.您可能要检查一下.

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