I see that Apple maps it to a PostScript dictionary namespace, but this
seems limitative for the implementation, when almost all foundries are
converting now their Type1 fonts to OpenType, which is much more
efficient, but still requires some entry point with a numeric assignment
(a glyph ID will still require an input codepoint to seek relevant glyphs,
and a PUA still requires a table of conversion from ranges to that
font-specific PUA, and a TrueType font not marked as Unicode
compatible would use direct glyph IDs from a externally defined
character set similar to legacy charsets, except that they can't be
mapped to Unicode).
I'm still convinced that these glyphs are much more informative than
a default glyph showing a "?", a white rectangle, or a black losange
with a mirrored white "?"... And Unicode also uses these glyphs
in the index page for its charmaps, but they are shown as poor
bitmaps (may be the PDF or book version use your glyphs in
a document-embedded font)
How were your glyphs contributed? With SVG graphics containing
character objects and drawing primitives (it seems the simplest
way to derive them, using the table shown in Apple's web page,
with some exceptions for unassigned, reserved, forbidden or
surrogates symbols which require a distinct design)?
