Gergely Nagy 43d08629cf process_unicode: Replace register_hex32
It turns out that register_hex32 did not work reliably, and some systems
only allow 7 chars after the unicode magic sequence, while others allow
8. To remedy the situation, store the codes as strings, and type those
in instead of doing bit shifting magic.
