These my words were intended only to you, not to the email list, because 
it is out of topic. Never mind, let we discuss about it.

In 2012, on my keyboard, I am unable to find the characters you mentioned.

This Knuth's message from 30 years ago is still applicable today. It is 
ergonomic, visible, robust and understandable. You can use real alpha 
instead of \alpha etc., but you need to use some mouse activies or some 
invisible editor-dependent shorthands. This is demonstration of the 
unanderstanding of the principles of TeX. If you insist on the usage of 
these real characters in TeX (and derivatives), you are on your own.
This will work if UTF8 input is proper configured. But this is no reason 
of refusing the good principles from 30 years ago.
