pch as single character

Dear friends - using windows xp and R1.6.1
when doing
x <- 12
as.character(x)
[1] "12"
plot(1,2,pch=as.character(x))
the interesting point is marked with: 1 whereas I would like to see
12.
In par() is specified under pch:

     Either an integer specifying a symbol or a single character to be
     used as the default in plotting points

How is that overridden ?

You cannot. Instead, use text() to plot strings as in

 plot(..., type="n")
 text(..., as.character(x))
