When typing text (e.g. a French axis label in ggplot) in the code pane of an R view node, I've observed that when the image is returned back to KNIME, the same text is returned with encoding problems (typical French characters such as é or à come back as @ or other equivalents in a different code page).
What bugs me is that the text encoding preferences in both R and KNIME is set to UTF-8, so this should not happen. This happens on Windows (cp1252) but also on Mac OS X (utf-8). What's going on here? Is it possible to control the encoding of the R node code pane? Please note that this does not happen with text via a table but only via code. Worse even, searching for such characters in data sent to R via code becomes impossible as well. Same problems with German ä ö ü.
