I think that Omega does this, though I cannot say more, not being an
Omega user myself. From
/usr/local/teTeX/share/texmf.tetex/doc/omega/base/doc-1.12.ps, p. 6:
½, on the other hand, allows 256 (2^8) font families, each font of 65
536 (2^16) characters. So, in addition to the TEX math font primitives,
which continue to work, there are 16-bit versions:
[...]
¥ \omathchar 27-bit number : Generates a math character with 27-bit
math code;
[...]
where
[...]
¥ 27-bit number refers to value 0x8000000 or a triple
Ð 3 bits for math category,
Ð 8 bits for font family,
Ð 16 bits for character in font,
called a math code;

For my specific problem, here's finally the dirty fix I've used, based
on amsmath.sty's \text command allowing straightforward input of text
in maths:
\usepackage{amsmath}
\DeclareFontFamily{U}{appsym}{}
\DeclareFontShape{U}{appsym}{m}{n}{<-> "Apple\space Symbols"}{}
\DeclareTextFontCommand{\applesym}
{\normalfont\fontencoding{U}\fontfamily{appsym}\selectfont}
\DeclareRobustCommand{\textapplehighplus} {\applesym{\char"253C}}
\DeclareRobustCommand{\textappleblacksquare} {\applesym{\char"25A0}}
\DeclareRobustCommand{\textapplewhitesquare} {\applesym{\char"25A1}}
\DeclareRobustCommand{\textappleblackdiamond}{\applesym{\char"25C6}}
\DeclareRobustCommand{\textapplewhitediamond}{\applesym{\char"25C7}}
\DeclareRobustCommand{\textapplewhitecircle} {\applesym{\char"25CB}}
\DeclareRobustCommand{\textappleblackcircle} {\applesym{\char"25CF}}
\DeclareRobustCommand{\applehighplus} {\text{\textapplehighplus}}
\DeclareRobustCommand{\appleblacksquare} {\text{\textappleblacksquare}}
\DeclareRobustCommand{\applewhitesquare} {\text{\textapplewhitesquare}}
\DeclareRobustCommand{\appleblackdiamond}{\text{\textappleblackdiamond}}
\DeclareRobustCommand{\applewhitediamond}{\text{\textapplewhitediamond}}
\DeclareRobustCommand{\applewhitecircle} {\text{\textapplewhitecircle}}
\DeclareRobustCommand{\appleblackcircle} {\text{\textappleblackcircle}}
This provides better compatibility with existing plain
TeX/LaTeX/amssymb.sty math symbols, allowing the replacement of these
symbols by Apple's ones:
% For plain TeX and standard LaTeX
\def\bigcirc{\applewhitecircle}
% For latexsym.sty
\def\Box{\applewhitesquare}
\def\Diamond{\applewhitediamond}
% For amssymb.sty
\def\square{\applewhitesquare}
\def\blacksquare{\appleblacksquare}
\def\lozenge{\applewhitediamond}
\def\blacklozenge{\appleblackdiamond}
Thanks for your clarification,
Bruno
