+Subject: [PATCH] libcody: Make it buildable by C++11 to C++26
+
+The following builds with -std=c++11 and c++14 and c++17 and c++20 and c++23
+and c++26.
+
+I see the u8 string literals are mixed e.g. with strerror, so in
+-fexec-charset=IBM1047 there will still be garbage, so am not 100% sure if
+the u8 literals everywhere are worth it either.
+
+2025-11-21 Jakub Jelinek <jakub@redhat.com>
+
+ * cody.hh (S2C): For __cpp_char8_t >= 201811 use char8_t instead of
+ char in argument type.
+ (MessageBuffer::Space): Revert 2025-11-15 change.
+ (MessageBuffer::Append): For __cpp_char8_t >= 201811 add overload
+ with char8_t const * type of first argument.
+ (Packet::Packet): Similarly for first argument.
+ * client.cc (CommunicationError, Client::ProcessResponse,
+ Client::Connect, ConnectResponse, PathnameResponse, OKResponse,
+ IncludeTranslateResponse): Cast u8 string literals to (const char *)
+ where needed.
+ * server.cc (Server::ProcessRequests, ConnectRequest): Likewise.
