Unreal titles end in their own libc fatal path with the UTF-16 LowLevelFatalError message in a register, and the crash report shows only the first 64 bytes of it as hex words, so the message is lost (#4238: Demon Slayer PPSA03490, Stray PPSA02100). For every general register that points at readable memory starting with at least four printable ASCII characters, as UTF-16LE or as single bytes, the report now prints the text up to a NUL, the first other character, 512 characters or the end of readable memory (each page is checked with VirtualQuery before it is read).
