Note also that 0x00 is mapped to a graphic character (@) *if* followed
by a non-0x00 (using a carriage return if there are no more printable
characters before the end of the (normally fixed) length terminated
string). Otherwise ((0x00)*<eos>) it is mapped to nothing.
(Not really suitable for an ICU ucnv-conversion, IIUC.)

Note also that the fallback for (most) Greek letters is the same-looking
uppercase Latin letter.
