[API Proposal]: Add ReadOnlySequence<char> overload for WriteRawValue #102491
Description
Background and motivation
In #68223, two overloads for Utf8JsonWriter were proposed, one for ReadOnlySequence<byte> and one for ReadOnlySequence<char>. The latter was rejected due to the necessary surrogate pair state handling while writing the ReadOnlySpan<char> segments.
However, #67337 is currently underway to add the building blocks and state handling for that. Adding the rejected overload now seems like an easy addition.
API Proposal
namespace System.Text.Json
{
public sealed partial class Utf8JsonWriter
{
+ public void WriteRawValue(ReadOnlySequence<char> json, bool skipInputValidation = false);
}
}API Usage
I could avoid building an entire in-memory, contiguous string just to have it written out as JSON. Other proposals like #97570 or #87362 would tie in very nicely as well.

#67377 is implemented. Where can I send the cake for bribery?

Duplicate of #68223; this API is available since .NET 8.

This is wrong. The requested overload is the one specifically dropped during review. There is only a
byteoverload, not one forchar.#68223 (comment)
