maybe one could keep character storage in (variable length) UTF format
throughout? Actually what would happen if the control sequence names
would be stored without input conversion in the pool with their original
UTF format? The hash would still work with UTF codes. Problems are e. g.
how to replace the eqtb area with the first 256 characters? Maybe also
use there a multi-byte sequence with a "single character" attribute?
