regex - 涉及特殊字符的 Google 应用脚本搜索未终止的括号错误

Question

我的程序有以下行，我用另一个字符串替换部分字符串。

for('condition'){    
Searched_in_Text_Mod = Searched_in_Text_Mod.replace(new RegExp('\\b'+split_search_key+'\\b','g')," ");
}

只要没有特殊字符，该代码就可以正常工作。

只要 split_search_key 有任何特殊字符，替换操作就会按如下方式终止：（记录器输出和执行记录）

我意识到它与正则表达式有关。但我自己无法解决。帮助将不胜感激。
