Quick and dirty (works in Linux xterm -u, ruby 1.8.7):

ruby -Ku -e "(0x410...0x430).each {|x| puts [x].pack('U')}"

The -K option is 'u' for setting the encoding to unicode, same as
setting '$KCODE=3D"u"' at the beginning of the code.

Array#pack is used because for Integer.chr, 1040ff are out of range.

Hope this helps,

t.
