You get that error because you're using double quotes around a string
containing double quotes, and not escaping them. With that string,
using single quotes on the outside should be fine:
showNonASCII('ggplot(df, aes(x = x)) + geom_histogram(aes(y =
..density..)), binwidth = 1, colour = "black", fill = "white")')
