How do I convert a UCS2 string into UTF8?

Question

How to convert a string that is in UCS2 (2 bytes per character) into a UTF8 string in Ruby?

Answer 1

Because chars in most cases string in UCS2 encoding can be represented as UTF-16 string (in UTF-16 char with codes bigger than 0x10000 is rarely used) I think use of Iconv is better way to convert strings. Sample code:

require 'iconv'

ic = Iconv.new 'UTF-8', 'UTF-16'
utf8string = ic.iconv ucs2string
