Questions About Token and Path

I looked at the following 2 specifications and got the following information:

2.2 Basic Rules

4.1.1. Syntax

The token and path cannot contain CTL. The regular expressions of the two are as follows:

TOKEN_RE = %r"\A[[!-~]&&[^()<>@,;:\\\"/?=\[\]{}]]+\z"
PATH_VALUE_RE = %r"\A[[ -~]&&[^;]]*\z"

What's the difference between the following two uses? How do you match CTLs?

[!-~]
[ -~]

从 issue 中链接的 RFC 部分以及报告中显示的 TOKEN_RE 和 PATH_VALUE_RE 表达式开始。阐明 [!-~] 和 [ -~] 之间的区别，并解释 CTL 字符是如何进行匹配的；未指定文件、测试或具体的代码更改。
