fail uploading my shiny app #123

Thanks for reporting this! Can you paste the Chinese characters and/or the expression causing the problem into the issue? (We want to be sure we're testing with the same ones when we try to reproduce this, so we'll copy/paste from your text.) |
|
No problem! I'll provide an easy example below so that you can reproduce the same issue. Note: If I run
If you need any further help to test Chinese character, please let me know. :) |

Unfortunately I was not able to reproduce this! I deployed your app from a Windows machine without any problems. https://jonathan.shinyapps.io/shinychars/ Can you paste your RStudio version and sessionInfo()? |
|
Absolutely, @jmcphers . https://yenping.shinyapps.io/chinese_char_demo/ Here's my RStudio version and sessionInfo(): BTW, did you deploy the app successfully with one .R file (app.R), or deploy it with separate files (ui.R and server.R)? |
|
Looks like you're on an older version of the package -- rsconnect 0.4.5 is the latest. Do you still see the error with the newest version? |
|
Unfortunately the error still exists after installing the latest version of I loaded the Where could I possibly do wrong? Here's my complete app.R file that was deployed to shinyapps.io: https://yenping.shinyapps.io/hchart/ sessionInfo(): |

Hi, I have the same error (fail lint(), dependent libraries aren't installed) on Japanese UTF-8 characters. The errors occur both my file and following official script (https://github.com/rstudio/shiny-examples/tree/master/022-unicode-chinese). My file is attached (please rename .txt to .R). Regards, |
|
Can you try explicitly marking the encoding as UTF-8? You should be able to do so with: I can reproduce the errors seen when working within a Japanese locale + the default encoding option set ( |
|
Hi, Kevin Thank you for your reply. As I have seen following article, I didn't try setting options(encoding). Better to guide the following might be helpful. Regards, |
|
I wonder if Perhaps we can have an option |
|
Yes, that helps much. |
|
@jin-tkomoda: one other option that might be useful here -- what if you try setting This will tell R to assume that files are saved with UTF-8 encoding, and so the default behavior of the various 'read' routines will assume the files are saved with UTF-8 encoding (as opposed to the system encoding). Of course, R's handling of UTF-8 strings has some pitfalls on Windows so this will be a bandaid more than anything. |
|
Normally (of my usecase), all .R files are UTF-8. But some CSVs and some text-stream contain japanese local encodings, so it is unsuited for default setting. |

Hi, @kevinushey is there any news on this ? I encountered the same issue. It seems to come from
You could try Not sure how to deal with this. Encoding issue is not easy. I will open an issue in |

I think we want to specify the encoding directly in the Note that Note that the default argument we have is Here's a test script that illustrates this: options(encoding = "native.enc")
# write some UTF-8 encoded content to a file, preserving
# the UTF-8 encoding (don't attempt to re-encode)
contents <- "\"這是一個直方圖\""
tempfile <- tempfile()
writeLines(contents, con = tempfile, useBytes = TRUE)
# try parsing the file
parse(tempfile)
parse(tempfile)[[1]]
parse(tempfile, encoding = "UTF-8")
parse(tempfile, encoding = "UTF-8")[[1]]
# try parsing from a connection, but set the encoding
parse(file(tempfile))
parse(file(tempfile))[[1]]
parse(file(tempfile, encoding = "UTF-8"))
parse(file(tempfile, encoding = "UTF-8"))[[1]]
# convince ourselves we did write the content as UTF-8
input <- readChar(tempfile, file.info(tempfile)$size, useBytes = TRUE)
Encoding(input) <- "UTF-8"
inputAnd the output I see: tl;dr: Packrat should probably try parsing with |

When I try that with French on Windows, things are different as the file is not written initially in UTF-8 if I play your example options(encoding = "native.enc")
# write some content in French with special french character
contents <- "\"Sélectionner des pâtes dans sa tête\""
tempfile <- tempfile()
writeLines(contents, con = tempfile, useBytes = TRUE)
# check the encoding
input <- readChar(tempfile, file.info(tempfile)$size, useBytes = TRUE)
Encoding(input) <- "UTF-8"
input
Encoding(input) <- "Latin1"
input
# try parsing the file
parse(tempfile)
parse(tempfile)[[1]]
parse(tempfile, encoding = "UTF-8")
parse(tempfile, encoding = "UTF-8")[[1]]
parse(tempfile, encoding = "latin1")
parse(tempfile, encoding = "latin1")[[1]]

parse(file(tempfile))[[1]]
parse(file(tempfile, encoding = "UTF-8"))
parse(file(tempfile, encoding = "UTF-8"))[[1]]
parse(file(tempfile, encoding = "latin1"))
parse(file(tempfile, encoding = "latin1"))[[1]]
# try parsing with readLines
readLines(tempfile)
readLines(tempfile, encoding = "UTF-8")
readLines(tempfile, encoding = "Latin1")resultsIf I try to force writing to UTF-8 to create a UTF-8 file as tempfile <- tempfile()
contents_utf8 <- iconv(contents, to = "UTF-8")
Encoding(contents_utf8)
writeLines(contents_utf8, con = tempfile, useBytes = T)
input <- readChar(tempfile, file.info(tempfile)$size, useBytes = TRUE)
Encoding(input) <- "UTF-8"

parse(file(tempfile, encoding = "UTF-8"))[[1]]
parse(file(tempfile, encoding = "latin1"))

contents <- c("library(tibble)", "#Création table", "tab <- tibble(scénario = 1:3, résultat = 1:3)")

Hi, I have a error when I connect my RStudio with shinyapp.io . It tells me: Error in curl::curl_fetch_memory(url, handle = handle) : How can I solve this? |

Hello all, let me join in the fray. I have seen this warning Now, I know that |

Hi! Any updates on the best way to do this? My ShinyApp reads in several csv files, most of them with non-ASCII characters (german Umlaute). I have saved all of the relevant r-scripts and csv files in UTF-8 encoding, and have also set options(encoding = "UTF-8") before deploying the App, but I still get this error message.

Should be fixed by rstudio/packrat#647 |
Hi, I was trying to publish my shinyapp to shinyapps.io.
At first, I got this problem, and sort of figured it out by setting the encoding of the R object loading from .rda to UTF-8.
But the same problem shows when I have some Chinese character in the app.R file.
In short, the following will work:
However, this will not (adding some Chinese character in the string):
and here's the messages on console:
(I have already set the whole app.R file to UTF-8, but it doesn't work.)
Can you help me with this?
Thanks!
