How do I (unconditionally) enable unicode support in busybox?

That set up does not work for sed, although it sometimes works.
The most mysterious thing is that it sometimes works and what
I need to do to get it to work in /init in an initrd.

In his last few posts in this thread, Harald Becker confirms this
is a problem.  He also suggested I use "wc -m" instead of:

    sed 's/./x/g' | wc -c

Or my tr hack.

The "wc -m" solution always works (for me) so my problem is solved.
But there is still a strange problem with sed and unicode that
Harald was able to reproduce.


Peace, James
