I am sorry for leading you down the wrong way with my advice. It turns
out that no 8-bit Type-1 encoding known to pdf() can represent both
'Lubomír Kubáček' and 'Anders Ågren':

lapply(
 setNames(nm = c(
  'latin1', 'cp1252', 'latin2', 'latin7',
  'latin-9', 'CP1250', 'CP1257'
 )), function(enc)
  iconv(enc2utf8(c(
   'Lubomír Kubáček', 'Anders Ågren'
  )), 'UTF-8', enc, toRaw = TRUE)
) |> sapply(lengths)
# one of the two strings cannot be represented, returning a NULL:
#      latin1 cp1252 latin2 latin7 latin-9 CP1250 CP1257
# [1,]      0      0     15      0       0     15      0
# [2,]     12     12      0     12      12      0     12

While it may still be possible to give extra parameters to pdf() to use
a font encoding that covers all the relevant characters, it seems
easier to switch to cairo_pdf() for your multi-lingual plots. Place the
following somewhere in the beginning of the vignette:

<<results=hide,echo=FALSE>>=
my.Swd <- function(name, width, height, ...)
 grDevices::cairo_pdf(
  filename = paste(name, "pdf", sep = "."),
  width = width, height = height
 )
@
\SweaveOpts{grdevice=my.Swd,pdf=FALSE}

This should define a new plot device function for Sweave, one that
handles more Unicode characters correctly.

This e-mail arrived in plain text, thank you!
