Subject: Re: A question about Iconv arguments

I've managed to solve this problem like this:

require "rubygems"
require "rio"
require 'iconv'
	

def to_hex(number)
	number=number.abs
	binary=''
        while number>0
		digit=number%16
		if digit<10
			binary<<digit.to_s
		elsif digit==10
			binary<<'A%'
		elsif digit==11
			binary<<'B%'
		elsif digit==12
			binary<<'C%'
		elsif digit==13
			binary<<'D%'
		elsif digit==14
			binary<<'E%'
		elsif digit==15
			binary<<'F%'
		end
		number=(number-digit)/16
	end
	return binary.reverse.gsub(/%([A-F])%([A-F])/,'%\1\2')
end

class String
	def wiki_addr
		converted_doc = Iconv.new('utf-8', 'latin1').iconv(self)
		res=''
		converted_doc.split(//).each{|x| 
			if /[a-zA-Z0-9\_ ]/.match(x)
				res<<x
			else
				res<<to_hex(x[0])
			end
		}
		return res
	end
end


doc ="venerd�"
doc.wiki_addr
rio("http://it.wikipedia.org/wiki/"+ doc.wiki_addr)>rio("a.html")

Best regards,

Axel
