Disallow obscure ranges in character classes.
configuration in plugin:clean-regex/recommended: "error"
The range operator (the - inside character classes) can easily be misused
(most unintentionally) to construct non-obvious character class. This rule will
disallow all but obvious uses of the range operator.
Examples of valid code for this rule:
/[a-z]/
/[J-O]/
/[1-9]/
/[\x00-\x40]/
/[\0-\uFFFF]/
/[\0-\u{10FFFF}]/u
/[\1-\5]/
/[\cA-\cZ]/Examples of invalid code for this rule:
/[A-\x43]/ // what's \x43? Bring me my ASCII table!
/[\41-\x45]/ // the minimum isn't hexadecimal
/[*/+-^&|]/ // because of +-^, it also matches all characters A-Z (among others)
