Emacs Lisp: Chinese Char To Reference Link
We need a command to change the character under cursor into several HTML links.
<div class="chineseXL"><span lang="zh">我</span> <span class="en"><a href="https://translate.google.com/#zh-CN|en|我">Translate</a> • <a href="https://en.wiktionary.org/wiki/我">Wiktionary</a></span></div>

This is useful for writing blog on languages and linguistics.
Here's the code:
(defun xah-words-chinese-linkify () "Make the Chinese character before cursor into Chinese dictionary reference links. URL `http://xahlee.info/emacs/emacs/elisp_chinese_char_linkify.html' Version 2020-11-24 2021-05-02" (interactive) (let ( ($template "<div class=\"chineseXL\"><span lang=\"zh\">▮</span> <span class=\"en\"><a href=\"https://translate.google.com/#zh-CN|en|▮\">Translate</a> • <a href=\"https://en.wiktionary.org/wiki/▮\">Wiktionary</a></span></div>" ) ($char (buffer-substring-no-properties (- (point) 1) (point)))) (delete-char -1) (insert (replace-regexp-in-string "▮" $char $template))))
This is truely a time saver.
URL Encoding of Chinese
Note: technically, Chinese chars in a URL should be URL Encoded.
(A Chinese character should become bytes in hexadecimal from the char's UTF-8 encoding. The char 中's UTF-8 encoding is 3 bytes of the following hexadecimal: E4 B8 AD.)
However, i think the situation of percent encoding is a abomination. [see Problems of Symbol Congestion in Computer Languages; ASCII Jam vs Unicode] I decided to not botch my Chinese chars in URL. This does not cause practical problems.
