the lower 8 rows are a separate set of recoloured 8859-1 chars.
if we're loading for the fallback then we're loading this data for quake compatibility,
so we grab only the first 4 rows of each set of chars (128 low chars, 128 high chars).
if we're loading a proper charset, then we load only the first set of chars, we can recolour the rest anyway (com_parseutf8 will do so anyway).
as a final note, parsing iso8859-1 french/german/etc as utf8 will generally result in decoding errors which can gracefully revert to 8859-1 safely. If this premise fails too much, we can always change the parser for different charsets - the engine always uses unicode and thus 8859-1 internally.
