Re: a question about drawing wchar_t with SDL_TTF

replying to myself… as usual, you can search for a solution a whole day and when you finally give up and ask for help, you bump into the solution while closing tabs on stackoverflow :-)

the solution is dead simple :


	typedef std::basic_string<Uint16, std::char_traits<Uint16>, std::allocator<Uint16> > u16string;
	u16string utext( m_text.begin(), m_text.end() );
	SDL_Surface *msg1Sur = TTF_RenderUNICODE_Blended_Wrapped(m_font->get_ttf_font(), utext.c_str(), m_fontcolor, (Uint32)m_force_width); 
	

i hope this helps others
