Resolves #3873

Is there a good way to create tests for this?

Good addition!
I see that implementation is inspired by .toIterator. Maybe it is possible to just wrap Iterator[Char] into a Reader and piggy-back .toIterator?

Regarding tests, you can take a look at how ZStream.toIterator is tested.

@simpadjo took the implementation patterns from ZInputStream I'll look into the toIterator tests (where are these these tests?), thanks!

semi-related, what's the special sbt foo to run the code formatter check locally?

sbt fmt

Yes, probably Reader has more capabilities than Iterator, so makes sense to implement it like that.
Then you could look at ZStream.toInputStream tests: https://github.com/zio/zio/blob/master/streams-tests/shared/src/test/scala/zio/stream/ZStreamSpec.scala#L2706

The best way to format the code is sbt prepare (see Contributors Guide).

Just found the toInputStream tests:

zio/streams-tests/shared/src/test/scala/zio/stream/ZStreamSpec.scala

Line 2706 in b5f1830

suite("toInputStream")(
adding it here for my reference.
