If the Python curses module is compiled in Unicode mode (if curses.unget_wch() is present), addch(int) calls the C function wadd_wch() or mvwadd_wch(), instead of waddch() or mvwaddch(). It looks like the *_wch() family does not support characters like curses.ACS_HLINE.

My commit fixes the issue.

@Nicholas.Cole: Can you please try the last development version (default branch)?

@georg.brandl: Can you please include the important fix 27b5bd5f0e4c in Python 3.3 final?
