Linux下的iconv函数_course

在做utf-8编码转成unicode，使用了iconv函数 下面是代码 #ifndef CODECONVERTER_H #define CODECONVERTER_H #include <iconv.

请教iconv函数的用法？_course

我要写一个函数，用iconv把unicode串转成gb2312,函数是这样的， // UCS2解码 // 输入: pSrc - 源编码串指针 //nSrcLength - 源编码串长度 // 输出:

iconv（）或utf8_encode如何使我的脚本UTF8友好？_course

linux下iconv函数编码转换_course

在字符编码转化中，将UTF8转化为gb2312的形式，我使用的iconv函数，代码如下： #include <iconv.h> #include <iostream> #include <string

linux下字符串中汉字utf-8转gb2312中使用iconv函数时，一直返回-1_course

这个问题困扰我很久，请高手指教，部分代码如下： int code_convert(char *from_charset,char *to_charset,char *inbuf,int inlen,c

C语言中字符编码转换类库libiconv的iconv函数到底应该怎么使用？_course

在C语言中使用iconv函数来转换字符串的字符编码，字符不多的时候可以执行一次iconv转换完成。 但字符串字符特别多的时候，一次执行只能转换开始的一小部分。我搜来搜去，大部分都是只能用于数据量少的解
