The only unusual characters Squeak uses are
U+2190 LEFTWARDS ARROW
U+2191 UPWARDS ARROW
which have been in Unicode since Unicode 1.0 at least.

Otherwise, Squeak uses the MacRoman character set, all of which
is covered by Unicode except the "Apple" character which Squeak
doesn't use for anything.

What "old pre Smalltalk-80 characters" does Squeak need?
