使用方式

iconv  -f GB2312 -t UTF-8  分治算法.txt > 分治算法2.txt

支持的编码类型

可以使用下面命令查看编码类型

iconv -l

PS : ISO-8859 有很多种分支，iconv 支持 ISO-8859-1、ISO-8859-10，但不支持 ISO-8859，否则可能报如下错误：

$ iconv  -f ISO-8859   -t UTF-8  分治算法.txt  [0]
iconv: iconv_open(UTF-8, ISO-8859): Invalid argument

这样就不会报错

iconv  -f ISO-8859-1   -t UTF-8  分治算法.txt

但具体文件编码类型，建议使用 enca 来查看，file 命令可能不准确

iconv 更多用法

$ iconv --help                                                                                                                  
iconv: unrecognized option `--help'
Usage:	iconv [-cs] -f <from_code> -t <to_code> [file ...]
	iconv -f <from_code> [-cs] [-t <to_code>] [file ...]
	iconv -t <to_code> [-cs] [-f <from_code>] [file ...]
	iconv -l

NAME
     iconv – codeset conversion utility

SYNOPSIS
     iconv [-cs] -f from_name -t to_name [file ...]
     iconv -f from_name [-cs] [-t to_name] [file ...]
     iconv -t to_name [-cs] [-f from_name] [file ...]
     iconv -l

DESCRIPTION
     The iconv utility converts the codeset of file (or from standard input if no file is specified) from codeset from_name to codeset to_name and outputs the converted text on standard output.

     The following options are available:

     -c    Prevent output of any invalid characters.  By default, iconv outputs an “invalid character” specified by the to_name codeset when it encounts a character which is valid in the from_name codeset
           but does not have a corresponding character in the to_name codeset.

     -f    Specifies the source codeset name as from_name.

     -l    Lists available codeset names.  Note that not all combinations of from_name and to_name are valid.

     -s    Silent.  By default, iconv outputs the number of “invalid characters” to standard error if they exist.  This option prevents this behaviour.

     -t    Specifies the destination codeset name as to_name.

EXIT STATUS
     The iconv utility exits 0 on success, and >0 if an error occurs.

EXAMPLES
     Convert file.txt from IBM273 to UTF-8 and save the result to converted.txt:

           iconv -f IBM273 -t UTF-8 file.txt > converted.txt

SEE ALSO

STANDARDS
     iconv conform to IEEE Std 1003.1-2008 (“POSIX.1”).

HISTORY
     iconv first appeared in NetBSD 2.0, and made its appearance in FreeBSD 9.0.
