You may have a look at https://github.com/Julien-Blanc-tgcm/jbc-json .

Do I understand this correctly, that jbc-json parses one character at a time and stores function pointers in the stack, calling through the function pointer for each character?

You understand correctly. IIRC i measured at the time i decided to go this way that it was not slower than the traditional switch / case statement. When i started this library i put safety requirements over speed. This is why in the first versions, there weren't even external api to parse more than one character at a time (a strong guarantee against buffer overflows). This has improved to allow for in-situ parsing, since memory use has been an important goal for me. There’s still plenty of room for improvements, however (for example, the default structure proposed to store parsed object is particularly inefficient and does not support allocators). Regards, Julien
