Doc Date 2026-08-23 Mailing Date 2026-09 Unassigned Author(s) Jan Schultke Target Audience LEWG Revisions R5 R4 Tracking issue View on GitHub Abstract Add `std::to_signed` and `std::to_unsigned` function templates in the style of `std::to_underlying`.
	P3688R7	ASCII character utilities	Jan Schultke J. Schultke , Corentin Jabot C. Jabot	LEWG	2026-08-23	2026-09
Doc Date 2026-08-23 Mailing Date 2026-09 Unassigned Author(s) Jan Schultke, Corentin Jabot Target Audience LEWG Revisions R6 R1 Tracking issue View on GitHub Abstract The utilities in `<cctype>` or `<locale>` are locale-specific, not `constexpr`, and provide no support for Unicode character types. We propose lightweight, locale-independent alternatives.
	P3876R3	Extending <charconv> support to more character types	Jan Schultke J. Schultke , Peter Bindels P. Bindels	LEWG	2026-08-31	2026-09
Doc Date 2026-08-31 Mailing Date 2026-09 Unassigned Author(s) Jan Schultke, Peter Bindels Target Audience LEWG Revisions R2 R1 Tracking issue View on GitHub Abstract `std::to_chars` and `std::from_chars` currently only provide support for `char`, which causes several usability problems. This paper proposes to extend support to all other character types, with essentially the same behavior.

Doc Date 2026-09-21 Mailing Date 2026-09 Unassigned Author(s) Jan Schultke Target Audience LEWG Revisions R0 Tracking issue View on GitHub Abstract This paper supersedes [[P2827R1]](https://wg21%2elink/p2827r1) and fixes [[LWG3081]](https://wg21%2elink/LWG3081), [[LWG3082]](https://wg21%2elink/LWG3082), and [[LWG3456]](https://wg21%2elink/LWG3456). It is intended as a defect report for C++17. The handling of floating-point overflow and underflow in `std::from_chars` is inconsistent; the implementations diverge from each other, and every imple
