Jetbrains全系列IDE使用 1年只要46元 售后保障 童叟无欺
1、windows平台下
#ifdef _WIN32
int CParserIni::ansi2utf8(const string& ansiStr, string& utf8Str)
{
int ret = kNoError;
do{
//CP_ACP(ANSI字符集)
if (ansiStr.empty()) BREAK_WITH_ERROR(kInvalidParameter);
//现将本地代码页转换成utf16
int wlen = MultiByteToWideChar(CP_ACP, 0, ansiStr.c_str(), -1, NULL, 0);
if (wlen == 0) BREAK_WITH_ERROR(kConvertError);
wchar_t *pwBuf = new wchar_t[wlen + 1];
memset(pwBuf, 0, sizeof(wchar_t)*(wlen + 1));
if (MultiByteToWideChar(CP_ACP, 0, ansiStr.c_str(), ansiStr.length(), pwBuf, wlen)==0)
BREAK_WITH_ERROR(kConvertError);
//再将utf16转换utf8
int len = WideCharToMultiByte(CP_UTF8, 0, pwBuf, -1, NULL, NULL, NULL, NULL);
if (len == 0) BREAK_WITH_ERROR(kConvertError);
char *pBuf = new char[len + 1];
memset(pBuf, 0, len + 1);
if (WideCharToMultiByte(CP_UTF8, 0, pwBuf, wlen, pBuf, len, NULL, NULL) == 0)
BREAK_WITH_ERROR(kConvertError);
utf8Str = pBuf;
delete[] pwBuf;
delete []pBuf;
pwBuf = NULL;
pBuf = NULL;
} while (0);
return ret;
}
int CParserIni::utf82ansi(const string& utf8Str, string& ansiStr)
{
int ret = kNoError;
do{
//将utf8转成utf16(wchar_t)
if (utf8Str.empty()) BREAK_WITH_ERROR(kInvalidParameter);
int wlen = MultiByteToWideChar(CP_UTF8, 0, utf8Str.c_str(), -1, NULL, NULL);
if (wlen == 0) BREAK_WITH_ERROR(kConvertError);
wchar_t *pwBuf = new wchar_t[wlen + 1];
memset(pwBuf, 0, sizeof(wchar_t)*(wlen + 1));
if (MultiByteToWideChar(CP_UTF8, 0, utf8Str.c_str(), utf8Str.length(), pwBuf, wlen) == 0)
BREAK_WITH_ERROR(kConvertError);
//将wchar_t转换成ANSI
int len = WideCharToMultiByte(CP_ACP, 0, pwBuf, -1, NULL, NULL, NULL, NULL);

delete[] pwBuf;
delete[] pBuf;
pwBuf = NULL;
pwBuf = NULL;
} while (0);
return ret;
}
#endif
2、linux平台下
mbstowcs()
wcstombs()
