{.tabset} does not support Chinese

[psychelzh]

Here I include an example rmarkdown text:

---
title: 你好世界
output: html_document
---

# 标题 {.tabset}

## 标签一

内容

## 标签二

内容

And the output is as follows:

But interestingly, when I substitute "一" and "二" with 1 and 2 respectively, it works!

---
title: 你好世界
output: html_document
---

# 标题 {.tabset}

## 标签1

内容

## 标签2

内容

Then the output is right. Further trials indicate that there must be one visible alphanum character at the end of each tab title if you want it be right.

You have to assign ID's manually to the tab titles, e.g.

---
title: 你好世界
output: html_document
---

# 标题 {.tabset}

## 标签一 {#tab-1}

内容

## 标签二 {#tab-2}

内容

This is because Pandoc cannot generate an ID when there are no alphanumeric characters in a section heading.

@yihui Thank you for you quick response. I wonder if these tab titles can be further used, too; e.g., cross-reference?

[yihui]

Without tabsets, you can use ID's to reference a section, e.g. [see Tab 1](#tab-1). But you cannot reference tab titles (at least for now).

[psychelzh]

I think I know it now. I will add a tab title to every tabs in a tabset, but I cannot reference these tabs (I think it okay for now); if I want to refence a tab, change it to a section (do not append {.tabset}). Am I right?

And by now it is also very useful even without reference. Thank you for developing these inspiring packages! @yihui

[yihui]

Your understanding is correct.

[psychelzh]

Thank you. After one-day trying this feature, I found that the tab titles could not be repeated, just as intuition, which is quite annoying when the number of tabs to display increases. I am wondering whether a better support for Chinese without tab names is possible or not, although acceptable if not.

[yihui]

I don't know what you mean by "the tab titles could not be repeated". I think tab titles should be different by definition, and I don't know why someone wants to use the same title for two different tabs.

[psychelzh]

I agree with you. But there is a misunderstanding. I meant to say that if there are more and more tabs to display, one have to add a unique tab title to each of them, which is an otherwise unnecessary demanding task.

[yihui]

Do you mean a unique ID or a unique title?

[psychelzh]

Unique ID.

To be clearer, what I expected is just the support of Chinese tabs without adding ID's.

[yihui]

That is not possible, because Pandoc cannot generate automatic ID's for headers that do not contain any alphanumeric characters (e.g. pure Chinese): http://pandoc.org/MANUAL.html#header-identifiers You will have to file a feature request to Pandoc.

[psychelzh]

I got it! And thank you very much for your kind response.

[psychelzh]

@yihui I am sorry to disturb you again, but I have filed an issue (jgm/pandoc#4452) at the Pandoc side. Then the developers there stated that Pandoc supports generating automatic identifiers for Chinese headers.

Here is the result:

% pandoc -t html
# 标题 {.tabset}

## 标签一

内容

## 标签二

内容
^D
<h1 id="标题" class="tabset">标题</h1>
<h2 id="标签一">标签一</h2>
<p>内容</p>
<h2 id="标签二">标签二</h2>
<p>内容</p>

Now I wonder what the true issue is.

[yihui]

Actually we enabled the ascii_identifiers extension. The tabs will work if you remove the extension:

---
title: 你好世界
output:
  html_document:
    md_extensions: -ascii_identifiers
---

# 标题 {.tabset}

## 标签一

内容1

## 标签二

内容2

Thank you. @yihui It is of great help! 👍
