c940a31e - Remove unreachable error branch by casting to UInt in parsing (#58480)

Remove unreachable error branch by casting to UInt in parsing (#58480) The `ncodeunits` field of substrings - and therefore also their size, cannot be negative. Ideally we would also remove the unnecessary checks in the other `tryparse` methods, that take start and end indices, but that should probably be rewritten to take a view, but that's a PR for another day.
