Using Gnu-iconv on Solaris and OpenSolaris
Gnu-iconv supports more encoding conversions and provides better performances for some conversions over the Solaris-iconv. E.g., currently, Solaris-iconv does not support the conversions between GB18030 and UCS-2BE, UCS-4LE/BE, UTF-16LE/BE; and the conversions of GB18030<->UTF-8 (UCS-2LE) in Gnu-iconv is two times faster. And Gnu-iconv has a star-shaped structure with some exceptions, which uses UCS-4 as the intermediary encoding. While Solaris-iconv has a peer-2-peer structure (with alias), it's really painful to add a new encoding.
So, you may want to use Gnu-iconv library. For Solaris 10/Nevada, you could download&install gnu-libiconv from www.sunfreeware.com, for opensolaris, you could install SUNWgnu-libiconv from pkg.opensolaris.org, but the OS.o package does not contain the header files.
You may notice that, the function symboles in gnu-libiconv, had been added the prefix of "lib", e.g., iconv_open -> libiconv_open. So, LD_PRELOAD and RUNPATH are not sufficient for replacing iconv(3) routines in libc. You need to make sure to include the "iconv.h" from gnu-libiconv.
和Solaris的iconv相比较，Gnu-iconv支持更多的编码转换，并且在某些编码转换上有更好的性能。例如，目前Solaris-iconv不支持从GB18030到UCS-2BE、UCS-4LE/BE和UTF-16LE/BE之间的转换；而GB18030<->UTF-8 (UCS-2LE)在Gnu-iconv中的转换速度，是Solaris-iconv的两倍。并且Gnu-iconv是一种星型结构（也有某些点到点的例外情况），它使用UCS-4作为中间转换的介质。而Solaris-iconv是一种点到点的结构（支持别名），因此添加一个新的编码实在是有些痛苦。
因此，你可能希望使用Gnu-iconv程序库。对Solaris 10/Nevada来说，你可以从www.sunfreeware.com下载并安装gnu-libiconv，对opensolaris你可以用pkg(1)从pkg.opensolaris.org上安装SUNWgnu-libiconv的程序包，不过这个包没有包括头文件。
你可能已经注意到了，gnu-libiconv中的符号名，都被加上了"lib"的前缀，例如iconv_open->libiconv_open。因此LD_PRELOAD和RUNPATH并不能替换libc中的iconv(3)调用。你必须确保include gnu-libiconv中的"iconv.h"头文件。
