Latin1 encoding errors when exporting with orca

I have a problem exporting plots using LATIN1 encoding for characters. When I produce the plot with the plotly command, it works well but when I export it with ocra, the encoding goes wrong for some characters (for example, le spanish 'á' becomes '�' as the character is unknown - � = Unicode U+FFFD replacement for unrecognized character). I export simply with:

orca(p, file = "myplot.png", width = 1000, height = 500, format = "png", scale = 1)

Should I do something within the orca command to plot those characters correctly?

Hi @mgfasel-unige, thanks for the report.

Could you share a full example, including the definition of the figure? Also, plotly.py doesn't have an orca function. What language/library are you using? Thanks!

Hi,

Thanks, I use the R plotly library.

Here is an example:

ex  <- data.frame(region = c("Pará", "Pará", "Pará", "Pará", "Pará", "Region2", "Region2", "Region2", "Region2", "Region2", "Region3", "Region3", "Region3", "Region3", "Region3"),
                  country = c("Brazil", "Brazil", "Brazil", "Brazil", "Brazil", "Country2", "Country2", "Country2", "Country2", "Country2", "Country3", "Country3", "Country3", "Country3", "Country3"),
                  var = c("VAR1", "VAR1", "VAR1", "VAR1", "VAR1", "VAR1", "VAR1", "VAR1", "VAR1", "VAR1", "VAR1", "VAR1", "VAR1", "VAR1", "VAR1"),
                  value = c(2,5,7,5,4,3,9,5,7,5,3,7,6,9,3))
p <- plot_ly(ex) %>%
  add_trace(x = ~region, y = ~value,
            color = ~country, fillcolor = ~country, opacity = 1.0,
            type = 'box', boxpoints = "all", jitter = 0.0,
            pointpos = 0, line = list(width = 1),
            marker = list(color = '#000000', opacity = .8, size = 2),
            orientation = "v", showlegend = T) %>%
  layout(xaxis = list(title = 'Region', tickangle = 270, zeroline = FALSE,
                      categoryorder = "array",
                      categoryarray = c(unique(ex$country))),
         yaxis = list(title = 'Value', zeroline = FALSE),
         boxmode = "group", boxgap = 0.05, boxgroupgap = 0.3,
         legend = list(bgcolor = 'transparent'))
p
plotly_IMAGE(p, width = 600, height = 400, format = "png", scale = 1, dpi = 600,
             out_file = paste0("D:/Ex01a.png"))
setwd(paste0("D:/"))
orca(p, file = paste0("Ex01b.png"),
     width = 600, height = 400, format = "png", scale = 1)

The plotly'IMAGE command results in:

While the orca command results in (note the á in the Pará label):

I understand now that this thread is for Python. I will post it for R. Thanks..

I posted the issue in the orca thread. You can delete it here if better. Thanks again.

Hi - we are currently trying to tidy up Plotly's public repositories to help us focus our efforts on things that will help users most. Since this issue has been sitting for several years, I'm going to close it. If it's still a concern, we'd be grateful if you could open a new issue (with a short reproducible example if appropriate) so that we can add it to our backlog. Thanks for your help - @gvwilson
