- * Document-class: Iconv
- *
- * == Summary
- *
- * Ruby extension for charset conversion.
- *
- * == Abstract
- *
- * Iconv is a wrapper class for the UNIX 95 <tt>iconv()</tt> function family,
- * which translates string between various encoding systems.
- *
- * See Open Group's on-line documents for more details.
- * * <tt>iconv.h</tt>: http://www.opengroup.org/onlinepubs/007908799/xsh/iconv.h.html
- * * <tt>iconv_open()</tt>: http://www.opengroup.org/onlinepubs/007908799/xsh/iconv_open.html
- * * <tt>iconv()</tt>: http://www.opengroup.org/onlinepubs/007908799/xsh/iconv.html
- * * <tt>iconv_close()</tt>: http://www.opengroup.org/onlinepubs/007908799/xsh/iconv_close.html
- *
- * Which coding systems are available is platform-dependent.
- *
- * == Examples
- *
- * 1. Instantiate a new Iconv and use method Iconv#iconv.
- *
- * cd = Iconv.new(to, from)
- * begin
- * input.each { |s| output << cd.iconv(s) }
- * output << cd.iconv(nil) # Don't forget this!
- * ensure
- * cd.close
- * end
- *
- * 2. Invoke Iconv.open with a block.
- *
- * Iconv.open(to, from) do |cd|
- * input.each { |s| output << cd.iconv(s) }
- * output << cd.iconv(nil)
- * end
- *
- * 3. Shorthand for (2).
- *
- * Iconv.iconv(to, from, *input.to_a)
- *
- * 4. Simple conversion between two charsets.
- *
- * converted_text = Iconv.new('iso-8859-15', 'utf-8').iconv(text)
