>Description:

When booting -current install media on an i386 PC, either virtual
(qemu) or physical, using the video console, sysinst attempts to
display some internactional characters, such as a "c" with cedilla in
"francais", but ends up dropping those characters altogether.  This
leaves the texts hard to read, and it causes subsequent line-drawing
characters to be shown in the wrong column, messing up the borders
around the selection menu.  A screenshot can be seen at

Although this is a cosmetic issue, it does affect the very first
screen NetBSD displays to a user attempting to install it, which
creates a rather bad first impression.  

>How-To-Repeat:

An easy way is using qemu (though I have verified that the bug also
affects physical hardware):

   ftp ftp://ftp.netbsd.org/pub/NetBSD-daily/HEAD/200901240002Z/iso/i386cd.iso
   qemu-img create wd0.img 384M
   qemu -hda wd0.img -cdrom i386cd.iso -boot d
