Don't be surprised then if you see the micro sign on all standard French keyboards of computers (even those sold today). This is the only Greek letter supported there. So this is not just old mechanical typewriters (and the old mechanical French typewriters, built by Rockwell or Olivetti, the micro sign was not present, there was also no exponent two, but there was a "Fr" condensed ligature symbol for the Franc currency unit, a symbol which has not been encoded in the UCS ; the micro sign only appeared much later, on the very first PC keyboards by IBM, in the early 1980's...) And I still don't know why OEMs thought at one time that it would be more important to place this symbol on a well definite key, while at the same time omitting the much more important œ ligature (and forgetting the support of accented capitals)...
