Ruby

Apparently markdown didn't work so well, but hopefully the gist of the issue is captured here.

For the issue, without this fix, it is likely not to find registry keys/values that have unicode in them. This is what we were seeing.

Looks like you may want to explore the same for RegQueryInfoKey as well. See https://msdn.microsoft.com/en-us/library/windows/desktop/ms724902.aspx

I would like to see this backported to Ruby 2.1 as well. Without it, registry keys and values cannot be deleted at all. This is a fairly large issue on Windows.

This issue is marked as ‘2.1: REQUIRED’.

Late to the party, but why was RegQueryInfoKey also update to use W? I am working on https://github.com/jruby/jruby/issues/7106 and cannot figure out how CRuby manages to locate RegQueryInfoKey when only the A and W versions should exist in the actual DLLs.

It seems unneeded because not using any WCHAR arguments.

It's done by fiddle.
