unicode flag not working for RegEx in Javascript-CodePudding

My code is unable to detect the usage of operators along with non-english characters:

const OPERATOR_REGEX = new RegExp(
  /(?!\B"[^"|“|”]*)\b(and|or|not|exclude)(?=.*[\s])\b(?![^"|“|”]*"\B)/,
  'giu'
);

const query1 = '(Java or "化粧" or 化粧品)';
const query2 = '(Java or 化粧 or 化粧品)';

console.log(query1.split(OPERATOR_REGEX));
console.log(query2.split(OPERATOR_REGEX));

Whereas the same code successfully detects all operators on regex101.com using the unicode flag: https://regex101.com/r/FC84BH/1

How can this be fixed for JS?

CodePudding user response：

Keeping in mind that

\b (word boundary) can be written as (?:(?<=^)(?=\w)|(?<=\w)(?=$)|(?<=\W)(?=\w)|(?<=\w)(?=\W)) and
\B (non-word boundary) can be written as (?:(?<=^)(?=\W)|(?<=\W)(?=$)|(?<=\W)(?=\W)|(?<=\w)(?=\w))

and that a Unicode-aware \w pattern is [\p{Alphabetic}\p{Mark}\p{Decimal_Number}\p{Connector_Punctuation}\p{Join_Control}] (see Replace certain arabic words in text string using Javascript), here is the ECMAScript 2018 solution:

const w = String.raw`[\p{Alphabetic}\p{Mark}\p{Decimal_Number}\p{Connector_Punctuation}\p{Join_Control}]`;
const nw = String.raw`[^\p{Alphabetic}\p{Mark}\p{Decimal_Number}\p{Connector_Punctuation}\p{Join_Control}]`;
const uwb = String.raw`(?:(?<=^)(?=${w})|(?<=${w})(?=$)|(?<=${nw})(?=${w})|(?<=${w})(?=${nw}))`;
const unwb = String.raw`(?:(?<=^)(?=${nw})|(?<=${nw})(?=$)|(?<=${nw})(?=${nw})|(?<=${w})(?=${w}))`;

const OPERATOR_REGEX = new RegExp(
  String.raw`(?!${unwb}"[^"“”]*)${uwb}(and|or|not|exclude)(?=.*\s)${uwb}(?![^"“”]*"${unwb})`,
  'giu'
);

const query1 = '(Java or "化粧" or 化粧品)';
const query2 = '(Java or 化粧 or 化粧品)';

console.log(query1.split(OPERATOR_REGEX));
console.log(query2.split(OPERATOR_REGEX));
