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. |
