iconv命令是用来转换文件的编码方式的(Convert encoding of given files from one encoding to another),比如它可以将UTF8编码的转换成GB18030的编码,反过来也行。JDK中也提供了类似的工具native2ascii。Linux下的iconv开发库包括iconv_open,iconv_close,iconv等C函数,可以用来在C/C++程序中很方便的转换字符编码,这在抓取网页的程序中很有用处,而iconv命令在调试此类程序时用得着。
首先,我们要知道支持的字符编码有哪些,这个可以用-l参数得到(List known coded character sets)。
格式:iconv -l
其次,是怎样转换,如下所示:
格式:iconv -f from-encoding -t to-encoding inputfile
上面的调用方式,会把输出打印在屏幕上,如果要输出到文件,可以像下面这样
格式:iconv -f from-encoding -t to-encoding inputfile -o outputfile
[root@new55 ~]# iconv -l
The following list contain all the coded character sets known. This does
not necessarily mean that all combinations of these names can be used for
the FROM and TO command line parameters. One coded character set can be
listed with several different names (aliases).

iconv: 未知 3345 处的非法输入序列
最后一行表明有错,改用下面的就会成功了。
[root@new55 ~]# curl -s http://codingstandards.iteye.com/ | iconv -f utf8 -t gb18030
此处省略输出。有兴趣的读者可以试一下,可以完整的显示整个页面的源代码。因为gbk是gb18030的子集,gb18030包含更多的字符。

有问题,用hexdump来看一下里面的字节,发现里面有ef bb bf的BOM信息,iconv不支持。

那就把前面三个字节去掉试试,果然可以了。
