But the Fortress programming language designers clearly see the need for
alternate forms of Unicode characters in user interfaces. Witness the
following additional Fortress language features:
* Fortress substitutes underscores for spaces in unicode character names.
So "GREEK SMALL LETTER PHI" becomes "GREEK_SMALL_LETTER_PHI" in Fortress.
* Fortress aliases many mathematical Unicode characters with shortened
"phi" for "GREEK_SMALL_LETTER_PHI"
"SUM" for "N-ARY SUMMATION"
* 'Additionally, all Unicode character names are aliased with names in
which the following substrings are elided:
* And ... "There are many sets of Unicode character names for which all
characters in the set share the same prefix. ... Furthermore, characters
with the same prefix are often typed together. To facilitate entering
characters with a common prefix, Fortress supports distribution of a
Unicode prefix over a sequence of character names."
