Note that it is known that there is variants of VIQR. |
| 238 |
One use "O*" / "U*" instead of "O+" / "U+". Other |
| 239 |
use "OO" / "UU". Since I don't know how these variants |
| 240 |
are used and inclution of these notation is incompatible, |
| 241 |
this version of this module does not implement these. |
