How do I do ASCII to EBCDIC translation in Ruby?

I am using Ruby 1.8.7 on Mac OS X.

How do I convert ASCII to EBCDIC encoding, to communicate with legacy system. Would I have to use to jruby?

You should use the Ruby iconv library (for Ruby versions before 2.0) or the iconv gem (for Ruby 2+) specifying EBCDIC-US as the codeset:

irb(main):001:0> require('iconv')
=> true
irb(main):002:0> x=Iconv.new('EBCDIC-US','ASCII')
=> #<Iconv:0x7fb4274d88d8>
irb(main):003:0> x.iconv("foo")
=> "\206\226\226"

You can upgrade but that doesn't necessarily solve the problem.

There are multiple flavors of EBCDIC (THANK YOU IBM!) so you'll need to identify the subset your mainframe uses.

One thing I learned to do when programming on the mainframe, oh so many years ago, was to call some of the mainframe sysops, and pick their brains. They deal with conversion from other codesets into EBCDIC all day long, and probably have a tool that can do it on the fly.

An alternative would be to see if they have something that can parse JSON or YAML. Convert your text to UTF-8, send it to the mainframe, let its translator convert from UTF-8 to EBCDIC.
