Simple Question: how can I convert UTF-8 strings (from REXML) to
iso8859-15?

Thanks
Andreas

You would think that was a simple question, but I don’t have a simple
answer. The YAML homepage mentions a Ruby interface to the Iconv
library, but the link it provides back to RAA doesn’t find anything.
Was there an Iconv library that disappeared??

Thanks, but that doesn’t help in this case. The referenced message
includes a pointer to a port of libiconv to Windows, but libiconv I
already have. What I don’t have is the code to use it from Ruby.
I could write an extension, but what confused me was the reference on
the YAML page. It seemed to imply that this had already been done, and
even had a link that should have taken me to the Ruby module
on RAA, but no such module was there.

Oh, sorry. I need to remove that link. The iconv lib is now included
with 1.8.0. WrItten by Nobu. If you need it for 1.6.8, I found the
link from FreeBSD ports (/usr/ports/converters/ruby-iconv):

http://member.nifty.ne.jp/nokada/archive/iconv-0.5.tar.gz

Also, please note that YAML 0.50 or newer don’t utilize iconv for
conversion and in fact doesn’t do any character set conversion.

This is out of date. The latest ruby-iconv for 1.6 is
contained in shim.

Oh! Well, in that case, the answer to the original question is simple.

require 'iconv'
iconv  = Iconv.new('ISO-8859-15', 'UTF-8')
latin9text = iconv.iconv(utf8text)

I find the (to, from) argument order counterintuitive, but that’s not Nobu’s
fault - it’s the order of the underlying C function iconv_open.

Agree. I often miss it too.
