This change implements support for additional named universal character escapes, aligning GCC’s C preprocessor (libcpp) with the C++29 standard as specified in P3733R1. The implementation updates the internal mapping of character escapes and adjusts associated test cases to reflect the new standard, ensuring correct preprocessing for C++29 code utilizing these advanced character representations.
