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

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 codesetbut 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 STATUSThe iconv utility exits 0 on success, and >0 if an error occurs.EXAMPLESConvert file.txt from IBM273 to UTF-8 and save the result to converted.txt:iconv -f IBM273 -t UTF-8 file.txt > converted.txtSEE ALSOmkcsmapper(1), mkesdb(1), iconv(3)STANDARDSiconv conform to IEEE Std 1003.1-2008 (“POSIX.1”).HISTORYiconv first appeared in NetBSD 2.0, and made its appearance in FreeBSD 9.0.macOS 15.1                                                                                    October 22, 2009
