[R] unicode&pdf font problem RESOLVED

Just to add to this (I've been looking through the archive) problem with display unicode fonts in pdf document in R

If you can use the Cairo package to create pdf on Mac, it seems quite happy with pushing unicode characters through (probably still font family dependant whether it will display)

	probstring <- c(' \u2264 0.2',' \u2268 0.4',' \u00FC 0.6',' \u2264 0.8',' \u2264 1.0')
	Cairo(type='pdf', file='outputs/demo.pdf', width=9,height=12, units='in', bg='transparent')
	plot(1:5,1:5, type='n')
	text(1:5,1:5,probstring)  
	dev.off()

?Cairo suggests encoding is ignored if you do try to set it.

cheers

Ben
