Yeah, though as I've started using it, I've quickly found that enough of Phobos doesn't support it yet, that it's problematic. e.g. https://issues.dlang.org/show_bug.cgi?id=15800 The situation will improve, but for the moment, the most reliable thing is still to use strings as ranges of dchar but special case functions for them so that they avoid decoding where necessary. The main problem is places like filter where if you _know_ that you're just dealing with ASCII but the code has to treat the string as a range of dchar anyway, because it has to decode to match what's expected of auto-decoding. To some extent, using std.string.representation gets around that, but it runs into problems similar to those of byCodeUnit. So, we have a ways to go. - Jonathan M Davis
