Forum: Ruby Writing text files with an explicit encoding (UTF-16LE)

Hey all,

I cant seem to find any documentation on how to write a text file to the
filesystem with an explicit encoding type? Can someone point me in the
right direction? Its a simple text file, but it *needs* to be UTF-16.

Cheers

Tim

require 'iconv'

converter = Iconv.new("UTF-16", "ISO-8859-15")
utf_16_str = converter.iconv('hello world')
p utf_16_str

--output:--
"\376\377\000h\000e\000l\000l\000o\000 \000w\000o\000r\000l\000d"

Whoops.  I overlooked the 'LE' in your title:

require 'iconv'

converter = Iconv.new("UTF-16LE", "ISO-8859-15")
utf_16_str = converter.iconv('hello world')
p utf_16_str

--output:--
"h\000e\000l\000l\000o\000 \000w\000o\000r\000l\000d\000"

So presumably something like the below would work?

converter = Iconv.new("UTF-16", "ISO-8859-15")
utf_16_str = converter.iconv('hello world')

File.open('example.txt', 'w') do |f|
   f.puts utf_16_str
end

Yup - it works :)

Thanks!
