Python has other lexical categories than identifier-chars eg operators.
Enriching that set is a somewhat different direction from 
enriching the identifier charset.

Note both these directions are valid bit different
This table http://www.unicode.org/charts/PDF/U2200.pdf
looks unpleasantly overfilled.  However good deal is stylistic differences
≥ vs ≧ and sometimes even indistinguishable ∈ vs ∊.

If we accept that python is more readable than Cobol, having a good
selection from the above makes for a programming language more readable in an
analogous manner.
