Did you select the right encoding when sending the email?

See for example:

send.mail(from = "Sender Name <[email protected]>",
                   to = "[email protected]",
                   subject = "A quote from Gandhi",
                   body = "In Hindi :  थोडा सा अभ्यास बहुत सारे उपदेशों से बेहतर है।
                   English translation: An ounce of practice is worth more than tons of preaching.",
                   encoding = "utf-8",
                   smtp = list(host.name = "smtp.gmail.com", port = 465, user.name = "gmail_username", passwd = "password", ssl = T),
               authenticate = TRUE,
                   send = TRUE)
`

I am having the similar problem. Trying to send file generated from R Markdown v2 and it shows incorrect characters. The idea was to send markdown file from Rmd as text with output: github_document

Solution with encoding = "utf-8" didn't worked for me, but notepad++ shows utf-8 encoding and righ letters in generated file. So I tried reading file to variable and setting it as body.

fileContent <- readLines("aterkoppling.md", encoding = "UTF-8")

That's not working because (but RStudio shows right text):

Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl, : java.lang.NoSuchMethodException: No suitable method for the given parameters In addition: Warning message: In if (file.exists(body)) body <- readChar(body, file.info(body)$size) : the condition has length > 1 and only the first element will be used

Any ideas?

@rpremraj yes,i added 'encoding='utf-8'' as it in your example,but not work for me ......

I've met the same problem.

Here is my simple Rmd-file (also saved in RStudio with UTF-8 encoding))

**тест** (ukrainian)
**test** (english)

Here is R-script for creating html-document and sending it via mailR:

library(knitr)
library(mailR)

knit2html(input = "encoding_test.Rmd", encoding = "UTF-8")

send.mail(
  from = "[email protected]",
  to = "[email protected]",
  subject = "encoding test",
  html = TRUE,
  body = "encoding_test.html",
  encoding = "utf-8",
  smtp = list(
    host.name = "smtp.gmail.com",
    port = 465,
    user.name = "myUsername",
    passwd = "myPassword",
    ssl = TRUE
  ),
  authenticate = TRUE,
  send = TRUE
)

When you open an html-document in a browser the encoding is correct, notepad++ shows aslo UTF-8 encoding both for html- and md- documents. But in a body of an e-mail it shows like this:

тест (ukrainian) test (english)

I also encountered the same problem, is there any solution? @rpremraj

[woldemarg]

It seems that problem with encoding of html-file via Rmail has dissapeared in R 3.4.3

I encountered the same problem,too. Is there any solution? @rpremraj

[MislavSag]

Same problem for me. There is still no solution to this problem?

[MislavSag]

I have found the solution:

sender <- "[email protected]"
recipients <- c("[email protected]")
send.mail(from = sender,
          to = recipients,
          subject = "R Markdown Report - rmarkdown",
          body = paste0(readLines("file.html", encoding = "UTF-8"), collapse = ""),
          encoding = "utf-8",
          html = TRUE,
          smtp = list(...),
          send = TRUE)
