下面小编就为大家带来一篇Linux下实现UTF-8和GB2312互相转换的方法。小编觉得挺不错的,现在就分享给大家,也给大家做个参考。一起跟随小编过来看看吧,祝大家游戏愉快哦
实例如下:
#include<iconv.h> #include <stdio.h>
 
#include<iconv.h>
using namespace std;
int utf8togb2312(const char *sourcebuf,size_t sourcelen,char *destbuf,size_t destlen) { 
 
iconv_t cd; 
 
if( (cd = iconv_open("gb2312","utf-8")) ==0 )  
 
  return -1; 
 
memset(destbuf,0,destlen); 
 
const char **source = &sourcebuf; 
 
char **dest = &destbuf;
if(-1 == iconv(cd,source,&sourcelen,dest,&destlen))  
 
  return -1; 
 
iconv_close(cd); 
 
return 0; 
 
}
int gb2312toutf8(const char *sourcebuf,size_t sourcelen,char *destbuf,size_t destlen) { 
 
iconv_t cd; if( (cd = iconv_open("utf-8","gb2312")) ==0 )  
 
return -1; memset(destbuf,0,destlen); 
 
const char **source = &sourcebuf; 
 
char **dest = &destbuf;
 if(-1 == iconv(cd,source,&sourcelen,dest,&destlen))  
 
return -1; 
 
iconv_close(cd); 
 
return 0; 
 
}
int main() { 
 
char line[80]; 
 
char dest_gb2312[200]; 
 
char dest_utf8[200]; 
 
int ret ; 
 
FILE *fp = fopen("love.txt","r"); 
 
if(fp == NULL) 
 
{  
 
printf("oh my dear,open fail...\n");  
 
return 1; 
 
}
 
 memset(line,0,80); 
 
if( NULL == fgets(line,80,fp)) 
 
{  
 
printf("oh fgets fail...\n");  
 
return 2; 
 
}
 
printf( "----- :%s\n",line );
 
ret = gb2312toutf8(line,strlen(line),dest_gb2312,200); 
 
// ret = gb2312toutf8(dest_gb2312,strlen(dest_gb2312),dest_utf8,80); 
 
printf( "ret=%d\n\n\n",ret); 
 
printf( "gb2312:%s\n",line ); 
 
printf( " utf-8:%s\n\n\n\n\n\n", dest_gb2312 );
 
 ret = utf8togb2312(dest_gb2312,strlen(dest_gb2312),dest_utf8,200); 
 
printf( "ret=%d\n\n\n ",ret); 
 
printf( " utf-8:%s\n ",dest_gb2312); 
 
printf( "gb2312:%s\n ",dest_utf8);
 
 return 0;
 
}
