Problem fixed:

for (( i = 0; i < 256; i++ )); do printf \\x$(printf 
"obase=16\n$i\n"|bc); done|iconv -f iso-8859-1 -t utf-8|perl -pe 
's/[^\t\n\x20-\xFF]|\xC2[\x80-\x9F]//g'|iconv -f utf-8 -t 
iso-8859-1|xxd

Outputs:

Probably 0x7F should also be stripped... also, I didn't check if 
everything between 0xA0-0xFF should actually be preserved -- I'll check 
UCD later...
