Quarto render error with chinese docs and knitr opts_chunk set in YAML heading

[goo]

A minimal demo:

---
title: "demo"
lang: zh
knitr:
  opts_chunk:
    collapse: false
format:
  gfm: default
---

第一行

第二行

-   第三行

-   第四行

-   第五行

The output

# demo

第一行二行 第三行 第四行 第五行

However, the expected output is

# demo

第一行

第二行

-   第三行

-   第四行

-   第五行

There are more strange behaviors when redering chinese docs with opts_chunk set. For example

• Spaces must not preseed or follow digits, otherwise a compile error or disappear of several chinese characters.

• Spaces must not appear at the end of a paragraph, otherwise may end up strange characters like �\<8c\>

• For unkown reasons, the final few sections or paragraphs may no be rendered.

It seems the problem is assosicated with two factors Chinese docs, and, opts_chunk seting, since:

• When rendering en docs (no Chinese character. lang does not matter ), no problem.

• When rendering chinese docs (including Chinese character. lang does not matter ), with no opts_chunk settings, no problem.

• When rendering chinese docs (including Chinese character. lang does not matter ), with opts_chunk set, the output messed up, including the following that I tried:

  • collapse: true

  • collapse: false

  • echo: true

  • echo: false
