Gentoo下打开windows txt文件中文乱码问题

Linux与Windows系统语言编码区别

在Linux操作系统下，我们有时打开在windows下的txt文件，发现在windows下能正常显示的txt文件出现了中文乱码。
出现这种情况的原因为两种操作系统的中文字符编码方式（压缩方式）不同，在windows环境中中文字符编码一般为gbk，而在linux环境中为utf8，这就导致了在windows下能正常显示txt文件在linux环境下打开呈现了乱码状态。

系统编码设置

locale.gen

文件

# /etc/locale.gen: list all of the locales you want to have on your system## The format of each line:# <locale> <charmap>## Where <locale> is a locale located in /usr/share/i18n/locales/ and# where <charmap> is a charmap located in /usr/share/i18n/charmaps/.## All blank lines and lines starting with # are ignored.## For the default list of supported combinations, see the file:# /usr/share/i18n/SUPPORTED## Whenever glibc is emerged, the locales listed here will be automatically# rebuilt for you.  After updating this file, you can simply run `locale-gen`# yourself instead of re-emerging glibc.en_US.UTF-8 UTF-8zh_CN.UTF-8 UTF-8

查看系统语言编码种类

目录下包含系统支持的编码语言种类

gentoo ~ # ls /usr/share/i18n/locales/en_US       en_GB     en_HK

解决方案

使用

iconv

命令进行文件编码转换，如乱码文件名为hello.txt，那么在终端输入如下命令：

iconv -f gbk -t utf8 hello.txt > hello.utf8.txt
