The ctype functions threw std::invalid_argument for any value below EOF, so a title passing a plain char with its high bit set, such as a UTF-8 byte, aborted. The libc.prx bundled with titles accepts -128 to -2: each class function returns 0 for them, as for 128 to 255 in the C locale, and toupper and tolower return them unchanged. Values outside -128 to 255 still throw. Co-Authored-By: Claude Opus 5.5 <[email protected]>
