Help getting around iconv on a PC

[Anders]

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:in
`require'
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:in
`require'
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:in
`require'
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:in
`require'
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:

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

Thanks, Dave! That did the trick.
