求一个C++实现的UTF8编码类


google好了几个出来，都不好用，教高手贴段代码，高分相送，回帖者有分，顶起

C/C++ code

iconv.
[解决办法]
iconv 和 楼上的楼上都行 ，用的简单的就用2L的
[解决办法]
顶起。貌似有人给出源码了
[解决办法]
这是我以前用iconv写的字符集转换代码：
C/C++ code
#include <jni.h>#include <iconv.h>#include <string>#include <iostream> #pragma comment(lib,"iconv.lib")int code_convert(char *from_charset,char *to_charset,const char *inbuf, size_t inlen,char *outbuf, size_t outlen){         iconv_t cd;         const char **pin = &inbuf;         char **pout = &outbuf;          cd = iconv_open(to_charset,from_charset);         if (cd==0) return -1;         memset(outbuf,0,outlen);         if (iconv(cd, pin, &inlen,pout, &outlen)==-1) return -1;         iconv_close(cd);         return 0;} /* UTF-8 to GB2312  */int u2g(const char *inbuf, size_t inlen, char *outbuf, size_t outlen){         return code_convert("UTF-8","GB2312",inbuf,inlen,outbuf,outlen);} /* GB2312 to UTF-8 */int g2u(const char *inbuf, size_t inlen, char *outbuf, size_t outlen){         return code_convert("GB2312", "UTF-8", inbuf, inlen, outbuf, outlen);}
