Is there a knitr option to force UTF-8 encoding in included R files?

Question

I am using Windows 7, R2.15.3 and RStudio 0.97.320 with knitr knitr_1.1.6 (downloaded after Yihui fixed the \'Encoding: knitr and child files\' issue on March 12)

Answer 1

Ideally I should have an encoding argument in read_chunk(), but since you were using UTF-8, this probably works:

read_chunk(lines = readLines("TestSpanishText.R", encoding = "UTF-8"))

Please try this first. If it does not work, I will add an encoding argument. Anyway, I'm sure this definitely works (it is just slightly longer):

con = file("TestSpanishText.R", encoding = "UTF-8")
read_chunk(con)
close(con)
