which I want to get AB closer without space:
------       ------            ----------     ------------
|     |      |      |          |  ————  |    | ——    ——  |
|  A  |      |  B   |          |  |A|B| |    | |A|   |B| |
|     |      |      |          |  ————  |    |  ——   ——  |
|     |      |      |  --->    |        |NOT |           |
|     |      |      |          |        |    |           |
|     |      |      |          |        |    |           |
|     |      |      |          |        |    |           |
------       ------            ------      --------
