javascript - 通过正则表达式分割(孟加拉语)字符串而不使用分隔符，零宽度前向查找不起作用

Question

实际上我也无法让它以英语运行。我正在寻找一个组合两个正则表达式的表达式:

const string = 'Joe shouted, \"The pitchforks are coming!\"';

zeroWidthSplitter = /(?=e)/g;  //splits before every "e"

string.split(zeroWidthSplitter) == 
    ["Jo", "e shout", "ed, \"Th", "e pitchforks ar", "e coming!"]  //true

wordRegex = /[a-zA-Z]+/g;    // matches all English letters, 
                             // discarding spaces and punctuation

string.match(wordRegex) ==
    ["Joe", "shouted", "The", "pitchforks", "are", "coming"]

我想要的是一个zeroWidthWordDelimiter，这样它的行为就像用单词边界分割一样，保持空格和标点符号与单词分开:

string.split(/(?:\b)/gm);

//the string is split strictly with words and non-words

0: "Joe"
1: " "
2: "shouted"
3: ", \""
4: "The"
5: " "
6: "pitchforks"
7: " "
8: "are"
9: " "
10: "coming"
11: "!"

但我希望分割一串外语(孟加拉语)字符，而这些字符无法被单词边界识别。
我可以成功地将单词分组，并通过将所有孟加拉语字母放入 [ 中来成功分组间隙。字符类]+
Wiktor 的建议是一个很大的改进，将 Angular 色分成非捕获组 (?:a|b|c|d)。这成功地对单词进行了分组，但丢失了标点符号。
Peter 的更灵活的正则表达式 /[^\p{Script=Bengali}]+/u 也是如此，它使用 Unicode Property Escapes

BengaliString = 'হঠাৎ একটা মেয়ে বাকি দু’জন কে কানে কানে বললো,“আমি যেমন টা করবো তোরা সেরকম আমার সাথে থাকবি ।”' ;

const BengaliRegex = /[ড়ঢ়ঁংঃঅআইঈউঊঋঌএঐওঔকখগঘঙচছজঝঞটঠডঢণতথদধনপফববভমমযরলশষসহািীুূৃৄেৈোৌ্ৎড়ঢ়য়]+/gm ;  //groups words

    //doesn't group multiple letters using +

const BengaliRegexPeter = /[^\p{Script=Bengali}]+/u ;
   //beautiful! but doesn't keep punctuation and spacing

console.log("Bengali Gaps Regex: " + BengaliString.split(BengaliGapsRegex));
console.log("Regex Delimiter: " + BengaliString.split(BengaliDelimiter));
console.log("Bengali Regex Wiktor: " + BengaliString.match(BengaliRegexWiktor));
console.log("Bengali Splitter Wiktor: "+ BengaliString.split(BengaliSplitterWiktor));
console.log("Regex Peter: " + BengaliString.split(BengaliRegexPeter));

使用此正则表达式模式来检测孟加拉字母:

/[\u0985-\u0994\u0995-\u09a7-\u09a8-\u09ce\u0981\u0982\u0983\u09e6-\u09ef-]/g
