Question

The error information is as follows:

The input must be a UTF-8 encoded text.
Error: pandoc document conversion failed with error 92

I made many attempts to solve this problem, but failed

Have you consider the package-devel mailing list? – IRTFM Mar 22 '22 at 05:10 — IRTFM, Mar 22 '22 at 05:10

The error message says it failed because "The input must be a UTF-8 encoded text." That's not the default on Windows, so you need to work out how to get the file into that encoding.

There are two possibilities. First, it might be that your input file is not in UTF-8. You should be able to ask whatever editor you are using to save it in that format. In RStudio, you use File | Save with encoding... and choose UTF-8.

That might not be sufficient. In versions of R on Windows prior to the upcoming 4.2.0, a lot of output is automatically changed to the default encoding, which is not UTF-8. You could try installing the development build from https://cloud.r-project.org/bin/windows/base/rdevel.html . That version should handle UTF-8 much more smoothly. If you do install it, you should probably also update RStudio; I'm not sure your version is compatible with the new R.

Hi！Your suggestions can solve this problem for me. I am truly grateful to you for what your suggsetions — Steven, Mar 23 '22 at 02:59
