Apache Common UrlValidator does not support unicode. alernative is avaliable?

Question

i try to url validation. but UrlValidator is does not support unicode. here is code

public static boolean isValidHttpUrl(String url) {
    String[] schemes =         


        

Answer 1

It doesn't support IDN. You need to convert URL to Punycode first. Try this,

  isValid = isValidHttpUrl(IDN.toASCII(url));

Answer 2

There may be a more recent RFC that supersedes this one, but technically speaking URLs do not suppor Unicode. RFC1738

The relevant section in particular:

No corresponding graphic US-ASCII:

URLs are written only with the graphic printable characters of the
US-ASCII coded character set. The octets 80-FF hexadecimal are not
used in US-ASCII, and the octets 00-1F and 7F hexadecimal represent
control characters; these must be encoded.
