This is what I get if I do a straight copy and paste on the following expression with Greek letters and the weak inequality sign. 2\[Alpha] + 3\[Pi] <= 3 It can be copied and pasted (I paste it back as Plain Text using Paste As to get the correct font size - but I think that is a result of some of my Windows settings.) The letters appear as proper Greek letters in the notebook. The real problem is when there is a boxed expression. Then I convert it to InputForm to give, for example, the following. Integrate[E^x, x] This will paste back in as is, that is as InputForm, but it can be converted to StandardForm with the boxed structures simply by placing the cursor in the cell and typing Shift-Ctrl-N. I'll admit that the longer expressions for Greek letters is not quite as nice in a posting but it can all be copied and pasted and works properly in notebooks for everyone. David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: Andrzej Kozlowski [mailto:akoz at mimuw.edu.pl] To: mathgroup at smc.vnet.net David, InputForm (and Copy As Text) have no effect at all on Greek symbols, at least on Mac OS X with Apple Mail (however, I don't think the e- mail client could have anything to do with this). The other thing that sometimes causes problems is the weak inequality sign: <= and in this case converting to InputForm does help. I sometimes forget to do this because after pasting the TraditinalForm of weak inequality into Mail it continues to look fine. However, in the case of Greek symbols there is no other choice that I know of but replacing them by Latin letters. I believe that doing this is up to the original poster of a message and not up to people responding to it.
