255 = U+FF are the so-called Fullwidth Latin Characters
(http://www.unicode.org/charts/PDF/UFF00.pdf)
they are "A" "B" "C" etc. but having the width of a Chinese character
(roughly "A ", "B ", "C "). Since they look rather ugly in non-CJK texts
and they have to match the width of the Chinese characters in the font,
they are only in CJK fonts.

32 = U+20 are general punctuation. I don't see a reason for those.

37 = U+25 are box drawing characters - no idea why those should be
included. http://www.unicode.org/charts/PDF/U2500.pdf

38 = U+26 are miscanllaneous symbols - no idea why those should be
included. http://www.unicode.org/charts/PDF/U2600.pdf
