Re: utf8 patch for mc, slang 2 version

[Bálint Kardos <kardosbalint gmail com>]

Hi, I've debuged it from the beginning, and:

screen.c 762:


// inserted

			wchar_t lonaka[100];
			memcpy(lonaka,buffer,txtlen*sizeof(wchar_t));
			lonaka[txtlen]=0;

// end inserted

		    printw ("%*s", still, "");

		    printw("%ls",lonaka);
	           //SLsmg_write_nwchars ((wchar_t *) buffer, txtlen);

		    printw ("%*s", len - txtwidth - still, "");


printw("/ls",lonaka); handles everything as expected, the right UTF-8
chars appeared on the screen. So text in the buffer is properly
encoded.
It is an Slang2 issue, but it's too compicated to figure out for the
first blick, the problem in the slsmg.c file.

Does anyone know why #define unix != 1 for darwin-ppc in mc (and/or) slang????
