There won't be many more ICONs (graphics) due to the limitations of 
representing/selecting each of them with a single alpha-numeric-punctuation 
ASCII character. Only a handful remain unassigned now.

There will only be an ever-increasing number of single ASCII character 
*OVERLAYS* on top of the EXISTING graphics.  In turn the overlays may or may 
not render correctly on a given client or web server.

Again, any such repository would have to store multiple file formats and 
graphics grid arrangements to accommodate the various clients and webservers 
that use the same symbols in different ways.

Every application uses the symbol set stored and/or rendered in a different way:


     o    Vector or bitmap

     o   Landscape or portrait rectangular grids with multiple cells,   one or 
two linear strips of cells 1 icon high,   several hundred "mini-graphics" in 
individual files.

     o   16x16 pixels square or 20x20 pixels square or 32x32 pixels square, etc.

     o   With or without overlay character(s) already embedded as part of the 
background bitmap (rather than as a separate ASCII text character drawn on top).

     o   In a variety of file formats (.BMP, .GIF, etc), with or without a 
transparency attribute.


As a result, there will never be a single universal ready-to-use symbol set.


Not to mention those apps where the symbol set is inaccessibly embedded into a 
compiled .EXE file.     Or embedded in unchangeable firmware like Kenwood radios.
