a lua table for converting unicode codepoints to codepage 437

unicode_to_cp437.lua

-- extracted from http://dwarffortresswiki.org/index.php/Character_table
-- (?:.*?\|){3}([a-z0-9]*.)(?:.*?\|){2}([0-9]*)}} extraction regex
-- you need to jump through some hoops to extract the unicode code points from lua strings, but it is doable
