True. I suppose if the half-enclosed digits were defined as halfwidth, it would work. It makes intuitive sense too, if a complete numbered circle is assumed to fill an ideographic cell. I'm not sure if rotation of the numbers would be desired, though. > The numbers however are used for noting or commenting a strategy, or the > placement order during a party. > > However for game notations purpose, rotation plays a significant role > (notably if those two part symbols are joined in a circle or disc: it can > make the difference between several distinct sets of stones, or it could be > used in a 4-players go variant (where black vs. white is not sufficient to > distinguish the players).

Rotation is definitely not salient in standard go kifu like it is in fairy chess notation. Go variants for more than 2 players are uncommon enough that I don't think any sort of standardized notation exists. > There are also go variants using stones that take a territory and block the > position but that cnanot be taken (both players can use them, but the > territory taken is not counted for any player. > These stones can also be placed randomly at start of the party over the > board to complicate the game, or there's a limited set of blocking stones > for each player that an choose when to play them instead of standard stones. > Those blocking stones are visually distinct, but identical for the two > players that have them at start of the party. Do you have any links? I'm interested in game design. > Although the classic rules of go are extremely simple, this game has a lot > of variants.

These are generally one-off inventions (or commercial products) so I don't think there's much need to consider their hypothetical variations on notation.
