POCO中文路径解决方法

POCO识别UTF8编码的字符串，所以直接用含有中文字符的C++字符串初始化Poco::Path或Poco::File是找不到文件路径的

同时Poco::File获取的文件名称也是UTF8编码的，C++输出为乱码，需将UTF8字符串转码

代码：

//!	将C++字符转为UTF8编码，主要用于Poco中文路径
/*!
	\param[in] str	需要转换的C++字符串
	\return	UTF8编码的字符串
*/
std::string strtoUTF8(const char* str)
{
#if defined (POCO_WIN32_UTF8) 
	std::string s = str;
	setlocale(LC_ALL, "chs");   
	const char* _Source = s.c_str();  
	size_t _Dsize = s.size() + 1;  
	Poco::UTF16Char *_Dest = new wchar_t[_Dsize];  
	wmemset(_Dest, 0, _Dsize);  
	mbstowcs(_Dest, _Source, _Dsize);
	Poco::UTF16String result = _Dest;  
	delete []_Dest;  
	setlocale(LC_ALL, "C"); 

	std::string utf8str;
	Poco::UnicodeConverter::convert(result, utf8str); 

	return utf8str;
#else
	return str;
#endif
}

//!	将UTF8编码的字符串转为C++字符串，主要用于输出Poco中文路径
/*!
	\param[in]	str8	需要转换的UTF8编码的字符串
	\return	C++字符串
*/
std::string UTF8toStr(std::string str8)
{
#if defined (POCO_WIN32_UTF8)  
	setlocale(LC_ALL, "chs");
	Poco::UTF16String str16;
	Poco::UnicodeConverter::convert(str8, str16);
	Poco::UTF16Char * char16 = (Poco::UTF16Char*)str16.c_str();
	size_t _Dsize = (str16.size() + 1) * 2;
	char * char8 = (char*)malloc(_Dsize);
	memset(char8, 0, _Dsize);
	wcstombs(char8, char16, _Dsize);

	std::string str = char8;
	delete[]char8;

	setlocale(LC_ALL, "C"); 

	return str;

#else
	return str8;
#endif
}

调用：

char * _str = "D:\\test路径测试\\";
Poco::Path _path(str2UTF8(_str));

std::string _str2 = UTF82Str(_path.getFileName());
