Hi,
I am sort of knew to this level of the discussion but am wondering at
the extent of the list. e.g I have been curious why some of the
symbols would not be allowed. I tend to look at the possibility of
symbolic labels as offering a possible alternative for non literate
people on special appliances.
Are there technical issues that make these problematic? Or is this a
policy decision that is being encapsulated into the technical solution?
thanks
a.
