ChartDirector 6.0在MFC下乱码问题

 

 

XYChart *c = new XYChart(640, 350);
char buffer1[256] = "";
UnicodeToUtf8(L"Realtime Chart with Zoom/Scroll and Track Line测试", buffer1);
c->addTitle(buffer1, "simsun.ttc", 18);

 

UnicodeToUtf8()函数实现如下：

void UnicodeToUtf8(const TCHAR *unicode, char *utf8)
{
　　int len = WideCharToMultiByte(CP_UTF8, 0, (const TCHAR *)unicode, -1, NULL, 0, NULL, NULL);

　　memset(utf8, 0, len * 2 + 2);
　　WideCharToMultiByte(CP_UTF8, 0, (const TCHAR *)unicode, -1, utf8, len, NULL, NULL);
}

void Utf8ToUnicode(const char *utf8, TCHAR *unicode)
{
　　int len = MultiByteToWideChar(CP_UTF8, 0, (const char *)utf8, -1, NULL, 0);

　　MultiByteToWideChar(CP_UTF8, NULL, utf8, -1, unicode, len);
}
