How to get terminal's Character Encoding
提问by Liang Wul
Now I change my gnome-terminal's character encoding to "GBK" (default it is UTF-8), but how can I get the value(character encoding) in my Linux?
现在我将 gnome 终端的字符编码更改为“GBK”（默认为 UTF-8），但是如何在 Linux 中获取值（字符编码）？
回答by Valdis
The terminal uses environment variablesto determine which character setto use, therefore you can determine it by looking at those variables:
终端使用环境变量来确定要使用的字符集，因此您可以通过查看这些变量来确定：
echo $LC_CTYPE
or
或者
echo $LANG
回答by Moreno
Check encoding and language:
检查编码和语言：
$ echo $LC_CTYPE
ISO-8859-1
$ echo $LANG
pt_BR
Get all languages:
获取所有语言：
$ locale -a
Change to pt_PT.utf8:
更改为 pt_PT.utf8：
$ export LC_ALL=pt_PT.utf8
$ export LANG="$LC_ALL"
回答by nyzm
localecommand with no arguments will print the values of all of the relevant environment variables except for LANGUAGE.
locale不带参数的命令将打印除 LANGUAGE 之外的所有相关环境变量的值。
For current encoding:
对于当前编码：
locale charmap
For available locales:
对于可用的语言环境：
locale -a
For available encodings:
对于可用的编码：
locale -m

To my knowledge, no.
据我所知，没有。
Circumstantial indications from $LC_CTYPE, localeand such might seem alluring, but these are completely separated from the encoding the terminal application (actually an emulator) happens to be using when displaying characters on the screen.
从间接指征$LC_CTYPE，locale并且这样的似乎诱人的，但这些都完全从编码终端应用程序（实际上是一个仿真器）分离发生在屏幕上显示字符时要使用。
They only way to detect encoding for sure is to output something only present in the encoding, e.g. ?, take a screenshot, analyze that image and check if the output character is correct.
他们确定检测编码的唯一方法是输出仅存在于编码中的内容，例如?，截取屏幕截图，分析该图像并检查输出字符是否正确。
So no, it's not possible, sadly.
所以不，很遗憾，这是不可能的。

If you have Python:
如果你有 Python：
python -c "import sys; print(sys.stdout.encoding)"
