Would you want to give range::views::iota(0, N) a try? An example use would be here:

contour/src/terminal/Grid.cpp

Lines 557 to 558 in abdae01

	for (auto const i: ranges::views::iota(0u, n.as<size_t>()))
	resetLine(baseLineOffset + LineOffset::cast_from(i), _defaultAttributes);

It avoids the need of having the iterator variable being noon-const (mutable) even though it is only used read-only in the loop body.

I am too dumb to actually make it work 😅 .

The compiler hates me. I'll give it a try in future PRs.

Note that only DWrite locator implements resolve. So basically you'll see zero font fallback for CJK if using DWrite shaper + Font config locator.

Also I think resolve here need to also pass fontDescription for bold/italic/etc.

I will catch up with them font config "resolve" implementation ASAP :)

I was a little more strict in reviewing. Most of it I think you can just take as suggestions and/or thoughts. :)
