Actually, I think you fell for a font bug. The character 222 in =20
iso8859-1 is the letter Thorn, and all letters may be part of =20
selectors. Set your code font to BitstreamVera to see the right =20
glyph. And use this to see all tokenish 8-bit characters (but be sure =20=

to view in in Vera):

((1 to: 255) select: [:i | (Character value: i) tokenish]) =20
asByteArray asString
