查看文件编码的工具enca for linux

介绍一个下查看文件编码的工具
在debian下通过apt-get install 就可以安装
它的说明如下:

is an Extremely Naive Charset Analyser. It detects character set and
encoding of text files and can also convert them to other encodings using
either a built-in converter or external libraries and tools like libiconv,
librecode, or cstocs.
Currently it supports Belarussian, Bulgarian, Croatian, Czech,
Estonian, Hungarian, Latvian, Lithuanian, Polish, Russian, Slovak,
Slovene, Ukrainian, Chinese, and some multibyte encodings independently
on language.
