The reset byte can be used for something more useful: it can be used as a key separator when sorting for example lists
of multicolumn output with priority between columns, even if each column is sorted in binary codepoint order.
The separator is actully not a character, but represents a metacharacter that will be higher than everything else, so
it can effectively terminate all binary encoded strings (when they are differentà, and maintain their relative
ordering; the following sort keys (further data columns) appended after it will not break the sort order of distinct
level-1 keys, but you'll be able to binary sort on the second column when two rows have binary identical first
It should never be used within the actual encoding of texts (and it is not even needed).
