How to filter the special characters, not including the French letters, using regular expressions

Question

我使用replace(/[^\\w\\s]|_/g, "").replace(/\\s+/g, " ")可以过滤所有特殊字符，但我不想过滤法语字母。

Answer 1

You can use this:

/[^\w\sàâäôéèëêïîçùûüÿæœÀÂÄÔÉÈËÊÏΟÇÙÛÜÆŒ]/g

You don't need special treatment for the _ as it is included in \\w
