As we find ourselves adding new fonts to Squeak (in part for 
aesthetic reasons, in part for licensing purposes), we are running 
into issues related to the fact that each font encodes "special 
glyphs" differently, and some fonts don't have these special glyphs 
at all.  It would be a good idea if we could adopt a standard 
encoding for Squeak Fonts, so to aid those converting new fonts for 
Squeak.

Squeak typically wants to have "straight line" single and double 
quotes, the underbar replaced with the assignment glyph, the caret 
replaced with the return glyph and so forth.  In TimesRoman, the 
original characters were "tucked into" an empty space in the font 
glyphs array.

As an aside, I'd really prefer if Squeak displayed "SOMETHING" to 
indicate that a non-printing character was struck.  Many times I have 
accidentally typed a control character or the like, which didn't 
display but was present in a string or symbol.  If outside of a 
literal, you simply get a confusing syntax error, but it does damning 
things elsewhere.  This could be accomplished simply by adding a 
"marker" character, leaving no empty spaces in the glyphs Form.

At any rate, it would be nice if we could settle on precisely what 
glyphs Squeak expects to have, and where, where we will or should 
"tuck away" the substituted glyphs for the Squeak-Unique symbols, and 
determine whether its a good idea to have "invisible" typable 
characters, or to fix it with a glyph (or some other means to display 
the same).  Once we settled on a "standard" encoding, presumably 
derived from a standard "standard" encoding of some sort, we can 
start building tools to facilitate the efforts of those importing 
Squeak fonts.
