[Rd] build package with unicode (farsi) strings

Thank you all for your valuable insights. The most viable workaround is a modification to the Hadley�s line of code:

stringi::stri_escape_unicode(letters_fa) %>%

paste0("'",.,"'",collapse=',') %>%


which then, the output string could be easily copied and pasted without manual editing. However, imagine you had to do this process to all of your English strings that you write daily! It is not that much productive. Is it?

I think R deserves a better support for internationalization and I know this implies fundamental revisions to the code to avoid the unecessary conversion to a (OS) native locale; i.e. directly reading/writing as unicode.

It's a little easier to do this with code:

letters_fa <- c('���','�','�','�','�','�','�','�','�','�','�','�')
#> \u0627\u0644\u0641
#> \u0628
#> \u067e
#> \u062a
#> \u062b
#> \u062c
#> \u0686
#> \u062d
#> \u062e
#> \u0631
#> \u0632
#> \u062f
