It surprises me to see you fall into the same kind of position that -- in the larger scale -- was the argument for keeping URLs to "ASCII-only". What is the scope of "the market"? If "the market" is "Alain", then the market penetration is 100%. If "the market" is "all keyboards on the planet" then, of course, the "market penetration" of keyboards that can type anything other than simple ASCII is still quite small. We are really talking about "character entry method" rather than "keyboard" since, as has been pointed out, with the "right software" it's possible to enter almost any kind of character from almost any kind of terminal; and "market penetration" might want to be clarified as to whether you're interested in the percentage of "things that are being sold in the marketplace now" or "existing, installed, usable", or at least some forecast of the latter.
