Hello,

this is due to different encodings used in the console and in the text
document you're searching in.
You can tell a Ruby script to use Unicode encoding by setting

$KCODE='u'

or use Iconv

http://www.ruby-doc.org/stdlib/libdoc/iconv/rdoc/classes/...

to convert between different encodings,e.g.,
if you need to convert from Western European ISO-8859-1 to
UTF-8:

require "Iconv"
include Iconv

puts "What do you want to search for?"
search_what=gets.chomp
search_what=Iconv.new('UTF-8', 'ISO-8859-1').iconv(search_what)

# now, search for search_what (in UTF-8 encoding ) in a text
# (which is also in UTF-8 encoding ) ...


Best regards,

Axel
