>Description:

When running any sysinst based install and selecting a non-english translation,
the display is missing all non-ASCII chars. The problem is old and had been
"fixed" (for now) by using CPPFLAGS.runetable.c+= -I 
${HACKSRC}/../../../lib/libc -DALL_80_TO_FF_SW1
in distrib/utils/libhack/Makefile.inc.

Somehow this does not work any more.
>How-To-Repeat:
boot any version of sysinst and select (for example) german messages.
(I checked i386 miniroot.kmod, sparc rootfs, sparc64 netbsd-INSTALL)

>Fix:
n/a
