C + + Chinese string to Unicode and UTF8

1. Description

Do system programming on Windows, and you will encounter problems dealing with Chinese strings. Most of the time Chinese characters are presented in multibyte-coded ways. For better compatibility or some special needs, such as appearing on a Web page. It is often necessary to convert it into Unicode or UTF8 format.

2. Code example 2.1 Chinese string to Unicode

/*************************************************************************int CN2Unicode(char *input,wchar_t *output)*功能：中文字符转换为unicode字符*参数：input，包含中文的字符串，output，Unicode字符串**************************************************************************/int CN2Unicode(char *input,wchar_t *output){    intstrlen(input);    //wchar_t *out = (wchar_t *) malloc(len*sizeof(wchar_t));    len=MultiByteToWideChar(CP_ACP,0,input,-1,output,MAX_PATH);    return1;}

2.2 Chinese character string turn UTF8

/*************************************************************************int CN2Utf8 (Char *input,char * Output) * Function: Chinese string converted to UTF8 String * parameter: input, String containing Chinese, Output,utf8 string *************************************************** **********************/intCn2utf8 (Char*input,Char*output) {intLen;wchar_t*out = (wchar_t*)malloc(len*sizeof(wchar_t)); Len = MultiByteToWideChar (CP_ACP,0, input,-1, Out,strlen(input) +1); WideCharToMultiByte (Cp_utf8,0, Out,wcslen (out), output,len,null,null);return 1;}
