Help getting around iconv on a PC


#1

I’ve just started using Ruby again, and maybe it’s because it’s been
awhile since I’ve used it, but I’ve gotten stuck. I want to use the
bloglines Webservice API. So, I downloaded and installed it as well as
simple-xml, which it uses. I run a simple test:

require ‘webservice/bloglines’
print “done!\n”

Ruby chokes, saying:

:/ruby/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in
require__': No such file to load -- iconv (LoadError) from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:inrequire’
from c:/ruby/lib/ruby/site_ruby/1.8/webservice/parser.rb:4
from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in
require__' from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:inrequire’
from c:/ruby/lib/ruby/site_ruby/1.8/webservice/restapi.rb:7
from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in
require__' from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:inrequire’
from c:/ruby/lib/ruby/site_ruby/1.8/webservice/bloglines.rb:3
from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in
require__' from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:inrequire’
from test.rbw:1

As far as I can tell from looking around the web, iconv is a Unix
library, and I’m on a PC running WinXP. How do I work around this? To
figure out what the parser is using iconv for, I’ve included the code
below. Any help would be greatly appreciated.

Thanks,

require ‘xmlsimple’
require ‘iconv’

handling invalid character

Replace from invalid character to `?’

(instead of numerical character reference).

Because REXML convert numerical character reference at parsing time.

class Iconv
def self.fix_malformed_characters(str)
iconv = Iconv.new(“UTF-8”, “UTF-8”)
out = “”
begin
out << iconv.iconv(str)
rescue Iconv::IllegalSequence => e
out << e.success
ch, str = e.failed.split(//n, 2)
out << if respond_to?(:unknown_unicode_handler)
unknown_unicode_handler(ch)
else
“?”
end
retry
end
return out
end
end

module WebService

class Parser
	def initialize
	end

	# for REXML
	def fix_encoding(xml_source)
		 xml_source.sub(/encoding="utf-8"\?>/i, 'encoding="UTF-8"?>')
	end

	def parse(xml_source)
		xml_source = fix_encoding(xml_source)
		xml_source = Iconv.fix_malformed_characters(xml_source)
		XmlSimple.xml_in(xml_source,
			{ 'ForceArray' => false, 'KeepRoot' => true }
		)
	end
end

end

I’ve put together a package to install iconv on a One-Click Ruby box
here:

Thanks, Dave! That did the trick.

Hi Anders, I haven’t used iconv on windows with Ruby, but I found this
googling…
