[R-lang] Re: Including IPA fonts in plots?

[Levy, Roger]

Got it; many thanks to both Ewan and Paul for pointing me to cairo_pdf.  This solved the problem.

Now: does anyone know if there's a way to get Sweave to use cairo devices instead of the default pdf and postscript devices?

Second, even if you could get the font to work, the pdf device chokes on Unicode, which was the original problem. (To see this, try using a non-TTF font that supports the glyph using the pdf device.) The cairo_pdf device (and other cairo devices) will support both TTF and Unicode.
