ggvis plots with ISO/IEC 8859-1

问题:

The default encoding for R is ISO/IEC 8859-1 which allows me to work with data containing letters such as å ä ö. However, ggvis does not allow such letters.

EDIT: Session info included

R version 3.2.3 (2015-12-10)
Platform: i386-w64-mingw32/i386 (32-bit)
Running under: Windows 7 (build 7601) Service Pack 1

locale:
[1] LC_COLLATE=Swedish_Sweden.1252  LC_CTYPE=Swedish_Sweden.1252    LC_MONETARY=Swedish_Sweden.1252 LC_NUMERIC=C

As expected, there is no problem using the r plot

data <- data.frame(Ålder = c(24:34), x = c(1:11))

plot(data$Ålder, data$x)

However, when using ggvis to do the same Å is replaced with a question mark

data %>%
  ggvis(~Ålder, ~x)%>%
  layer_points()

Is it possible to use ggvis with ISO/IEC 8859-1 encoding?

This behavior may appear on 32-bit machines.
