Doc Date 2026-09-18 Mailing Date 2026-09 Unassigned Author(s) Victor Zverovich Target Audience SG16 Tracking issue View on GitHub Abstract This paper proposes making `std::exception` and publicly derived exception types formattable with `std::format` and printable with `std::print`. It also specifies the encoding of library-generated parts of standard exception messages, resolving [LWG4087].
	P4235R0	Removing Digraphs	Matthias Wippich M. Wippich	EWG SG16 SG22	2026-09-22	2026-09
Doc Date 2026-09-22 Mailing Date 2026-09 Unassigned Author(s) Matthias Wippich Target Audience EWG SG16 SG22 Revisions R1 Tracking issue View on GitHub Abstract Digraphs are a complicated solution to a very old problem, which cause more problems than they solve in a modern environment. Digraphs also severely limit the design space of C++, although as we have seen with [[P2996]](https://www%2eopen-std%2eorg/jtc1/sc22/wg21/docs/papers/2025/p2996r13%2ehtml) we are already fine with special-casing our way out of this pickle.
	P4267R0	Formatting Enums, Upon Reflection	Victor Zverovich V. Zverovich	LEWG SG16	2026-08-20	2026-09
Doc Date 2026-08-20 Mailing Date 2026-09 Unassigned Author(s) Victor Zverovich Target Audience LEWG SG16 Revisions R1 Tracking issue View on GitHub Abstract Formatting an enumeration as its underlying type currently requires either a formatter specialization or an explicit conversion at every call site. [P3070] proposed `format_as`, an ADL-based customization point that makes this more convenient and allows the conversion to be performed before type erasure.
	P4345R0	Extending C++ with Unicode Mathematical Operators	Steve Downey S. Downey	EWG SG16 SG17	2026-09-22	2026-09
Doc Date 2026-09-22 Mailing Date 2026-09 Unassigned Author(s) Steve Downey Target Audience EWG SG16 SG17 Revisions R1 Tracking issue View on GitHub Abstract We propose that a user be able to declare `operator⊞` and write `a ⊞ b`. That is the whole feature: a frozen set of Unicode symbols that have never had meaning in C++ becomes available as operator tokens, and an operator drawn from that set is an ordinary overloadable function, found by ordinary lookup, called by ordinary overload resolution.
