I did it again... sigh. You will again get the "funny character"
unless you make sure the encoding of the e-mail is Unicode. The
problem is that I sometimes forget to convert the Mathematica code
to InputForm before pasting. If the message looks right in my mail
program (Apple's Mail) I assume it is going to be all right, but of
course this is true only if the receiving e-mail program interprets
the message as Unicode.
If the text is first converted to InputForm this problem does not
appear (except, I think, when one uses Greek letters). So here is the
above definition in InputForm:
p[f_, r_, k_] := Table[If[i <= j, Derivative[j - i][f][r]/(j - i)!,
0], {i, 1, k}, {j, 1, k}]
