Greek characters garbled when self_contained = FALSE

[yihui]

Originally reported at rstudio/DT#121. I simplified the repro:

---
title: "self_contained issue"
output:
  html_document:
    keep_md: yes
    self_contained: no

## Εισαγωγή

```{r}
library(htmltools)

```

Hello. I intended to open an issue to ask a UTF8-related question. When I type that in the console under Windows, it works fine:

> intToUtf8(981L)
[1] "ϕ"

But in a Rmd file I get:

## [1] "<U+03D5>"

@gd047 Your issue should be solved by updating all R packages now.

@stla Your issue is different. It is the same as r-lib/evaluate#66 and r-lib/evaluate#59.
