I am looking through std.unicode and I cant see a simpple way to do a strlen on an array of u8, except for perhaps to write my own code to iterate over an array or convert the string. Am I missing something simple? How do you get the real length of a string?
#Can we read the length of a utf8 string without encoding/decoding?

i.e. I can see we can make a view with an iterator? Do we then iterate and count, or is there a built in way to count items off an iterator?
const view = try unicode.Utf8View.init(w.items[start..w.items.len]);
view.iterator().....

Oh, thanks. I thought that meant count the length of the next character.

I am looking through `std.unicode` and I cant see a simpple way to do a `strlen`...
note that 'length' is something of a nebulous concept when working with unicode
if you want the number of grapheme clusters then you'll need to look outside of zig's standard library (one library i'm aware of: https://codeberg.org/atman/zg)
