void main(string[] args)

	system("pause");
}

2.////////////////////////

Please don't post to the bug list. It's really only meant for messages from bugzilla. You sign up for it if you want to see all of the bugzilla messages from when bugs are added or commented on or whatnot. Post on D.learn for questions about learning D and on D for discussions on the language and its development. This question should probably go on D.learn.

I'm not all that well versed in how you put unicode in your strings (rather than getting strings that have unicode in them from elsewhere - like user input), but my guess would be that you're not declaring your strings correctly, so they're not being treated as unicode. If you repost this on D.learn, odds are that someone there will know what you're doing wrong or perhaps even confirm that this is a dmd bug if that's really what's going on.
