This is done automatically for character arrays, which includes strings. wchar arrays wil iterate by UTF-16, and dchar arrays by UTF-32. If you have a byte/ubyte array you know to be unicode-encoded, convert it to char[] to iterate by code points.
Thanks for the response. I was looking for something where I don't have to manage buffers myself (e.g. when handling buffered file or socket I/O). It's really easy to find this functionality in e.g. Python, C#, Go, Kotlin, Java etc. but I'm surprised there doesn't seem to be a ready-to-go equivalent in D. For example, I can find D examples of opening files and reading a line at a time, but no examples of opening a file and reading Unicode chars one at a time. Perhaps I've just missed them?
