Should look something like this:

$KCODE='UTF8'
require 'jcode'

def parse_utf_string(text)
tempstr=""
text.each_char{|ch|
tempstr+=ch
if tempstr.length==20
yield tempstr
tempstr=""
end
}
yield tempstr if tempstr.length>0 #last chunk of file
end

parse_utf_string(File.open("test.txt").read){|chunk|
puts "20 bytes: #{chunk}"
}
