Regex for matching multilingual numbers not detecting Chinese numbers

问题

I have a method which detects whether a String is a number:

public static boolean isNumber(String num)
{
    return num.matches("(\\p{N})+");
}

The above method is successfully matching English, Hindi, Arabic numbers but fails to match Chinese numbers:

三十萬零二百五十 etc.

Is it possible to create a regex which can match a number from any language(or major languages)?

edit: the number won't be a decimal, it will be used to validate a phone number.

回答1:

as some have already pointed out in the comments, these are the words used for numbers, i.e. "one", "two", "three" etc. China introduced the indo-arabic numbers in the 19th century, so \p{N} should also match Chinese numbers. If you also want the literals, you should include them, as stribizhev suggested.
