Three s///g's per symbol suffice to convert from unicode to latex:

The last character in a line is easy:
	s/α$/\\alpha/g

When the unicode symbol precedes a letter, the command must be separated from 
the rest of the text with a space. The space is only used as a delimiter and 
ignored for spacing.
	s/α([A-Za-z])/\\alpha $1/g

If there's no letter after the symbol, no need for a space.
	s/α([^A-Za-z])/\\alpha$1/g
