		std::wstring &	res
	)			const

Parameters:

[in]	s	The string to convert
[out]	The	converted string

Returns:

Non-zero if there no errors or zero if s is not a valid UTF-8 string

std::string Transcoding::trEncodeUTF8

(

const std::wstring &

s

)

const

Parameters:

[in]

s

The string to encode

s

)

const

Parameters:

[in]

s

The string to translate

std::wstring Transcoding::trReadUTF8

(

const std::string &

s

)

const

This method decodes string and if the input value is not a valid UTF-8 sequence it will add questions marks in illegal places
