No, I am not using the "minus" from the Greek alphabet, I selected the 
character "-" from the tablet entitled "Greek alphabet" available from the 
"Maths" tablet. The "Greek alpabet" tablet includes many mathematical 
operators and symbols in addition to the Greek alphabet.

Amaya should make the necessary declaration or use the numerical reference, 
not I.

However, the reported bug is that, in the case described, Amaya does not 
generate the symbolic variable "&minus;" as it does in other cases when 
this character is selected, but the character macron.
