Problems using pipes in array

[Wooltown]

In one dimensional array, the text after the pipe will be removed, but in a two dimensional array, the text will occur in the following cell/column, see attached example.

How can I have a "|" in a cell in an array ?

#Include <Array.au3>

DIM $xx[9]
$xx[0] = "ABC|DEF"
;$xx[1] = "GHI|JKL"
$xx[2] = "MNO|PQR"
redim $xx[4]
_Arraydisplay($xx)

DIM $yy[9][3]
$yy[0][0] = 2
$yy[0][1] = 1
$yy[1][1] = "ABC|DEF"
_Arraydisplay($yy)

That exactly the reason what there is a before last parameter that can be use to change the separator needed used when displying the info by a listview control.
Perhaps the doc need more adice on this potential conflict.
