使用iconv 转换编码

在linux下经常遇到编码问题，有时可以统一使用iconv把编码转换一下，使用方法如下：

Usage: iconv [OPTION…] [FILE…]
Convert encoding of given files from one encoding to another.

Input/Output format specification:

-f, –from-code=NAME       encoding of original text  
-t, –to-code=NAME         encoding for output

Information:
-l, –list                 list all known coded character sets

Output control:

-c                         omit invalid characters from output  
-o, –output=FILE          output file  
-s, –silent               suppress warnings  

–verbose              print progress information

-?, –help                 Give this help list
–usage                Give a short usage message
-V, –version              Print program version

e.g:

iconv -f gbk -t utf8 -o a.txt xx.txt
