   grid q1
|domain error: glqextentw
|   wid=.    qextentwm CellDFmt
   grid q2

that works... So grid q2 shows me the grid but not grid q1 ???

The answer is in the Unicode support of J.
Here it is:
  $5!:5 <'q1'
346
  $5!:5 <'q2'
102
  5!:5 <'q1'
3 5$(u: 65 108 105 97 115);(u: 65 108 105 97 115);(u: 65 108 105 97 115);(u:
65 108 105 97 115);(u: 65 108 105 97 115);(u: 65 108 105 97 115);(u: 65 108
105 97 115);(u: 65 108 105 97 115);(u: 65 108 105 97 115);(u: 65 108 105 97
115);(u: 65 108 105 97 115)...
  5!:5 <'q2'
3 5$<;._1 ' Alias Alias Alias Alias Alias Alias Alias Alias Alias Alias
Alias Alias Alias Alias Alias'

The final answer is:
  q3=: 1&u:&.>q1
Grid q3 will work now :)
