Re: Human stupidity or is this a regression?
Lionello Lunesu: I could have sworn this used to work. Is my memory failing me, or was this a deliberate change at some point? Perhaps a regression? It's not a regression, it's a locked-in design mistake. Write it like this and try again: foreach (dchar d; "你好") Bye, bearophile

But D being D, the default should be safe and correct. I feel we could take this breaking change since it would not silently change the code to do something else. You'll get prompted and we could special case the error message to give a meaningful hint. L

D.learn newsgroup is not fit for such requests. Bye, bearophile

It is impossible for it to be "correct", unless with a very specific definition of "correct" which makes sense for some languages/locales and not others. As a challenge, try to define a "foreach" semantic that works "correctly" with the OP's code for Unicode composite characters, or Hebrew.

To be truly "correct" in the intuitive sense, use std.uni.byGrapheme. (Yes it's slow, but that's the price you pay for intuitive correctness.) T -- It always amuses me that Windows has a Safe Mode during bootup. Does that mean that Windows is normally unsafe?
