// Caveats - gdb prints any 8-bit value (meaning rust I8 and u8 values)
// as its numerical value along with its associated ASCII char, there
// doesn't seem to be any way around this. Also, gdb doesn't know
// about UTF-32 character encoding and will print a rust char as only
// its numerical value.
