Yes, I've used that before. However, in that case the special character
is part of the symbol font and corresponds to the letter "e" in the
normal font (Helvetica). In my case, the special character is in the
Helvetica font already, so I shouldn't even have to change fonts, but I
just don't know how to produce that character (since the keyboard
doesn't have a key for it) ...
What would probably work is to find the identifier of that annotation
and modify it programmatically (from the command line) using the
string() function. But it would be nice if there was an easy thing I
could type into the property sheet.
