The old X backend for Pango does exactly the same thing; it
creates "fonts" by default by merging on encoding, and
allows users to configure aliases with more general
patterns - the "sans" alias by default is configured to
be something like:
sans normal normal normal normal \
"-*-helvetica-medium-r-normal--*-*-*-*-*-*-*-*,\
-*-gulim-medium-r-normal--*-*-*-*-*-*-ksc5601.1987-0,\
-*-clearlyu-medium-r-normal--*-*-*-*-*-*-iso10646-1,\
-*-fixed-medium-r-normal--*-*-*-*-*-*-*-*,\
-kaist-iyagi-bold-r-normal--*-*-*-*-*-*-johab-1,\
-*-song ti-medium-r-normal--*-*-*-*-*-*-*-*,\
-freetype-unitamil-medium-r-normal--*-*-*-*-*-*-iso10646-tam,\
-*-devanagari-medium-r-normal--*-*-*-*-*-*-iso10646-dev,\
-*-gujarati-medium-r-normal--*-*-*-*-*-*-iso10646-guj,\
-*-gurmukhi-medium-r-normal--*-*-*-*-*-*-iso10646-gur,\
-*-bengali-medium-r-normal--*-*-*-*-*-*-iso10646-bng,\
-*-kannada-medium-r-normal--*-*-*-*-*-*-iso10646-kan,\
-*-burmese-medium-r-normal--*-*-*-*-*-*-iso10646-brm,\
-*-buginese-medium-r-normal--*-*-*-*-*-*-iso10646-bgn,\
-*-oriya-medium-r-normal--*-*-*-*-*-*-iso10646-ori,\
-daewoo-mincho-medium-r-normal--*-*-*-*-*-*-ksc5601.1987-0"
<shudder>
It turned out, however, when we got a decent font system,
that this wasn't the right place to put the standard aliases;
merging on encoding isn't needed if fonts can properly export
their encodings.
Instead the font lists for standard aliases went into the
mechanism for CSS2-style font lists.
