Comment:
I agree with (2). If digits aren't acceptable as leading characters we'd
better encode them.
I think the fix is simple:
* In `Encoding.zEncodeString` treat the first character specially, by
z-encoding even digits (which are not otherwise encode). A good encoding
would be `0 --> z0` etc.
* Similarly in decoding we'd need to treat the first character specially.
Alternatively we could *always* z-encode digits. But that seems overkill
(eg `base-3.5` would become `basezmz3ziz5` rather than (as now)
`basezm3zi5`). But it's no big deal either way.
Ian would you like to decide and execute?
Simon
