This is obsolete with the new pacman version 3.5!

Pacman (arch linux) uses a file based database with a lot
of small files. Some filesystems are awfully slow when 
accessing lots of small files, in general this is not 
that great of a deal because most of the applications 
store their information with more sense. Pacman doesn't 
care (it is a long well known problem), which means that 
sometimes you have to wait minutes before a search query 
completes (pacman -Ss).

    Code page 437 is the charset used by the original IBM PC,
    it includes a wide variety of graphical symbols for ascii 
    drawings.
    
    In this implementation I define unicode code points that
    match the original cp437 symbols. The table also includes
    the unique character name and if available the 7-bit
    US-ASCII character.
