Right, Suvayu, Unicodes are not universally supported.
So, what about coming back to basics ?
Just Ascii like that:

|  x |    sin(x/4) | Ascii        |
|----+-------------+--------------|
|  0 |           0 | WWWWWh       |
|  1 |  0.32719470 | WWWWWWWV     |

|  3 |  0.84147098 | WWWWWWWWWWW  |

#+TBLFM: $3='(orgtbl-ascii-draw $2 -0.9290145 0.99540796 12)

We remove Unicodes until someone comes with an idea.

Ivan, the LaTex \rule might be a (pretty) solution for the LaTex exporter.
But then we should also take care of all past and future exporters...
