What I mean is that it might not healthy expecting te computer
keyboard input to be able to supply the needed context in each key.
It might be faster to enter French without accents, letting the
computer software figuring them out, while retaining the ability to
enter them in special case by more complicated key combinations.
So hardware and software are intimately intertwined.

I just got private email, pointing out that on Mac OS X, anyone can
create their own keyboard layouts using the program Ukelele:
Regardless whether this might solve your problem, it just illustrates
the intimate connection between hardware and software.

Even though it is important to design special keyboard input methods
for certain special, often used, Unicode character subsets, it will
probably not be sufficient for general use. The problem arise when
character sets must be combined. Think of say a Russian mathematician
writing some lectures in Russian then, but which must also use
English words. Then that fellow needs to quickly switch between
English and Russian character sets, as well having quick access to
thousands of math characters. If the keyboards input methods are then
tied to special keyboards, then that will be problematic.
But on the hardware side, one can think of using as board essentially
a touch screen. Then any keyboard layout can be displayed on that
one. The problem with ouch methods is usually to provide sufficient
feel feedback to the human user. So it needs to augmented with
something such. Perhaps some kind of electrical current that gives
the feel of proximity and key borders.
