You still can't represent all lowercase letter shapes on a 14-segment display, but you can do all uppercase, so I'm assuming they went with that for consistency.
We can represent a "double storey" a like this:
___
|
___|
| |
|___|
It's also unclear why we couldn't have a 14 seg lower case m like this: _ _
| | |
| | |
Maybe for each character, have a link to a documented rationale.EDIT: Oh, look at the example font sheet featured in Wikipedia's Fourteen-segment-display page: it has these letters exactly as I say:

Only DSEG7 has lower case letters, and that's probably only to distinguish them from other characters or numbers (e.g. h/X, i/1, or o/0).

Well thought out font though, 7segg-chan is cute.
