Bookmark \@ref fails to work for multibyte strings about officedown

[davidgohel]

---
title: "Untitled"
output:
  officedown::rdocx_document:
    default
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

# Chapter1 {#ch1}

# Chapter2 {#ch2}

Refer to \@ref(ch1).

When \@ref(ch1) is surrounded by multibyte strings (e.g., Chinese characters), it would possibly encounter errors.

- Pure multibyte + ref: 上下\@ref(ch1)
- Example: 上a下\@ref(ch1)
- ref + multibyte: \@ref(ch1)。

Your issue is related to the fact you are not working with a UTF-8 encoded file.

R, R Markdown and Windows does not work well when encoding is not UTF-8.

Hi @madlogos,

I am aslo a Chinese user. The multibyte problem has also bothered me for a long time. Here is my trick for it:

1. Write @ref as usual;
2. Save the Rmd file and readr::read_lines it;
3. Match the strings containing "\\\\@ref\\([^\\)]+\\)" pattern;
4. Split it and make sure the "\\\\@ref\\([^\\)]+\\)" on a single line;
5. Save the character vector to a new Rmd file and render it with the format you like. Done!

For example, 请参考表\@ref(tab: coco)中的数据 should be splited as
[line 1] 请参考表
[line 2] \@ref(tab: coco)
[line 3] 中的数据

Well, I am not sure if this is an effective solution but it works for me. 😄

Yes, @davidgohel, you are right. Althougth the .Rmd file is in UTF-8, the OS is running on GBK encoding. When I change to bookdown::word_document2, the knitr engine manages to compile the file. But I still get ?? where the bookmark is supposed to appear.

You don't need to try new output format functions.

The result shown below is made with a Windows with french locale. But I made sure the file was encoded as UTF-8 (I am using readr::guess_encoding(), if not UTF-8 encoded, I can change it to UTF8 with fpeek::peek_iconv()).

Could you show the result of

readr::guess_encoding("your/rmd/file")

[madlogos]

The results are

no	encoding	confidence
1	UTF-8	1
2	windows-1252	0.28

@bishun945 thank you for the turn-around. Good stuff.

@madlogos I have tried another solution: just switch your system and MS Word language to English.
