Its not useful for most of Western europe either nowdays.

Is there a reason for not biting the bullet here and storing the
unmapped symbol then mapping it to the glyph when rendering. The days
where we had to worry about 8K more memory for the scrollback buffer are
dead and gone.
Basically I'd rather see us:
- Expand the kbd code to support the full set of behaviour (within
reason). It looks like the old behaviour can be expressed by keeping the
old format and allowing a new format (or mapping the old to the new when
the ioctl loads it)
- Expand the kbd code to allow caps/shift mapping by loaded table
- Store the true symbol not the glyph so we can cut/paste right
- Do the render mapping of symbols when needed when we actually render
That also means we get the right results if you move a live console from
text mode to graphical mode, or load different fonts and refresh.
