"A port of PDCurses must provide acs_map, a 128-element array of chtypes, with values laid out based on the Alternate Character Set of the VT100 (see curses.h)."

What is the standard and alternative sets exactly? The curses.h is encrypted with C defines, which I can't read - http://pdcurses.cvs.sourceforge.net/viewvc/pdcurses/PDCurses/curses.h?revision=1.298&view=markup (note that there is no way to give a link to the exact line, which is another reason why GitHub is better). An exact table with comparison or a reference to comparison would be more clear. -- anatoly t.
