Broken characters with pkgdown 1.5.0

[Bisaloo]

I just noticed strange characters in the pkgdown website for one of the packages I'm maintaining https://docs.ropensci.org/lightr/

In the NEWS page, you can see things like (this was a regression compared to pavo�s or test files provided by M.D. S.

These characters are absent from the source file so it's due to something during the conversion to HTML:

It's of course also obvious on the landing page / README, where the emojis in the titles are mangled up, but I don't want you to think that this issue is related to emojis only.

Please note that this issue is not related to rOpenSci since I can reproduce locally with devtools::build_site() (with pkgdown 1.5.0).

Note that I didn't have this issue until very recently (pkgdown 1.4.9000, didn't record the exact commit hash).

I will try to work on a reprex as soon as possible

Related: #1287?

I see the problem in another website but have not time to make a reprex myself yet, sorry.

Interestingly, I couldn't see this issue the first time my website was deployed with pkgdown 1.5.0. Now, I'm starting to wonder if this could be caused by r-lib/xml2#293.
