I do not know which database was used but a strange characters entered the field of an ArrayCtrl and it is diplayed as a little square (see picture)
From now on each QTF file containing the string in that field produces a mess
and panic of the user.
I tried to escape the string containing the strange character with
"\1" + string + "\1" and DeQtf(string) without success.
I would like to know if it is possible to prevent the insertion of this char and/or how to correct it once it is there, i.e. how to show a valid QTF file.
Perhaps, in such scenario, it would be acceptable to have the automatic replacement of the unwanted char with something else that let the user to be aware of where exactly the intruder is.
