Subject: Re: Iconv and incompatible encodings



Hello,
I was going crazy with this problem. I searched a lot and found some 
people with the same problem: Iconv works with irb but not in a ruby 
script.
The solution was take another way. For example, Daniel Lucraft 
(http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/306663) 
made 3 suggestions. The first one is use Ruby-GNOME2 library and:

require 'gtk2'
ascii = GLib.convert(string, "ASCII//translit", "UTF-8")

This not only worked for me, as the Iconv started to work as expected! 
For instance:
require 'iconv'
require 'gtk2'
puts Iconv.conv("ASCII//translit","UTF-8","áàâä")
gives 'aaaa'.

The second solution:
ascii = %x{echo "#{str}" | iconv -f "ISO-8859-1" -t 
"US-ASCII//TRANSLIT"}
also worked here.

The problem is that I'm not using a ruby script, I'm making an web page 
with mod_ruby. So, %x{} gives an 'Insecure operation' error and "require 
'gtk2'" gives:
/var/www/dev/q/test.rbx:12: Cannot open display:
/usr/lib/ruby/1.8/gtk2.rb:12
./lib.rb:31:in `require'

His last suggestion is to write your own wrapper. Of course I've not 
tried. Finally, I used the hack:
Unicode.normalize_KD(string).gsub(/[^\x00-\x7F]/n,'')
as described here: http://www.ruby-forum.com/topic/70827, and this looks 
to work fine to remove accents (but I'm not sure if the result is an 
ascii string)
