I receive the following error when attempting to compile a LaTeX document:

Package inputenc Error: Unicode character GenericError {(inputenc)}{Package inputenc Error: Unicode character (U+2069)

The cause of this error is a pdf image that I created in R. The title of the figure contains greek letters and subscripts. I have changed the pdf compiler from pdfLaTex to xeLaTeX and have included usepackage[utf8]{inputenc}, but neither works.

Has anyone had this issue and if so, how did you fix it?

Thanks,
Nate

Example Code: (test.Rnw)

documentclass{article}

usepackage{hyperref}

usepackage{amsmath, bm, multirow,booktabs,mathtools}

usepackage{setspace, relsize, booktabs, needspace, epic}

usepackage{longtable, color, colortbl, lscape, dcolumn}

usepackage[table]{xcolor}  



begin{document}

<<fig_test,eval=TRUE>>=

pdf("test_fig.pdf")

par(las=1, cex.axis=1.5,cex.lab=1.5,cex.main=1.5)

plot(x=c(1,5.1), y=c(0.75,3), typ='n',

main=expression(paste('X(',alpha[1],')',sep='')),ylab='',xlab='')

graphics.off()

@



begin{figure}

caption{Caption}

centering

includegraphics[scale=0.5]{"test_fig"}⁩

end{figure}



end{document}

The error is unrelated to the pdf insertion or Greek, you have a BIDI control character U+2069 POP DIRECTIONAL ISOLATE after test_fig"} in your source, if you retype that line just with ASCII it should be fine.
