如何了解「喜欢你，我也是」里写这个替代“秒怂”的词？ 我在看着书时遇到了下面不认识的字：


“呃，那个……”张侃侃听到“学姐”二字，秒～。她舔舔嘴唇尴尬地说，……
喜欢你，我也是，12页

我无法输入这个词：除了我的手机，我也尝试用QHanzi和Chinese Input，可是都不能识别“秒”右边的那个字。
为了对比，下面是Kindle版的相同部分。奇怪的是，那两词不一样。


“呃，那个……”张侃侃听到“学姐”二字，秒怂。她舔舔嘴唇尴尬地说，……
喜欢你，我也是，Kindle版

鉴于书里的语境，我猜这个词是“目瞪口呆”类似的意思，可是我根本不知道为什么出现不同。我也不知道“秒怂”是不是正确的词：在词典上我找不到这个词。

I know you're not going to be happy with this, but I'm going to write up an answer in English. First, at least.

First about digitization:
Amazon has the same problem you do. They don't know how to render the character. I haven't looked into it very deeply but it looks like they have issues with CJKV extensions. (Perhaps CJK Ext. A is more doable, but I'm not sure about B-G.)
 (⿸尸从) is a CJK Ext. C character.
CJK Ext. characters usually need special font support and that clearly hasn't been implemented into Amazon or Kindle products.

 can be found in Mandarin dictionaries:
Pleco

weak and incompetent

Oxford

weak by nature

CC-CEDICT

weak and incompetent

Perhaps the most well known word with this character is: 包.

For the sake of understanding you can consider 秒 two &quot;words,&quot; instead of one single word.
MDBG

秒
(coll.) instantly

&quot;秒 + verb&quot; has become a trend in neologisms. There are quite a few of these combinations, think: 秒懂，秒回，秒赞，秒睡，秒删, etc. 秒 is a combination of &quot;instant&quot; + &quot;cower.&quot;
