中文和unicode字符的相互转换

中文转换成unicode:

wchar_t* ChangeCODE(const wchar_t *lpText)

{

int nLen = wcslen(lpText)+1;

wchar_t *wcsTmp = new wchar_t[nLen];

memset(wcsTmp,0,nLen);

wcscpy_s(wcsTmp,nLen,lpText);

wchar_t *newTmp = new wchar_t[nLen*4];

memset(newTmp, 0, nLen*4);

for(int i=0; i<nLen-1; ++i)

{

wchar_t buf[5] = L"";

swprintf_s(buf,5, L"%04X", wcsTmp[i]);

wcscat(newTmp, buf);

}

delete []wcsTmp;

return newTmp;

}
