[Mageia-dev] Odd Window framing in curses part of install

[Frank Griffin]

Just a small thing, but the curses windows which appear at the start of 
isolinux prompting for the type of install, server address and so forth 
have suddenly had their borders filled with characters - "U" at the left 
corner, "A" along the top, and an upside-down question mark at the right 
corner.

I assume that curses is using ASCII extended graphics characters to draw 
the perimeter of the windows, but that the install itself is using UTF-8 
or some other character set which doesn't have them.
