Hexadecimal values support with \x escape

gsb4j/core/src/test/java/kg/net/bazi/gsb4j/url/CanonicalizationTest.java

Line 91 in 484645d

    
           //        Assert.assertEquals( "http://%01%80.com/", hashPrefix.canonicalize( "http://\\x01\\x80.com/" ) );

Please suggest why did you comment this line? Yes, Java doesn't support '\x' escape symbol for hexadecimal values, but you still can replace all '\x' occurrences with '%' symbol manually and then you will be able to unescape every hexadecimal value prefixed with ''%".

The other problem here is that you will probably face
java.lang.IllegalArgumentException: java.text.ParseException: A prohibited code point was found in the input
from java.net.IDN because of "�" uncoded symbol. This symbol is considered as "Prohibited"

Please take a look at line number 448 here:

Thanks!

Thanks @Vadimka29 for pointing out this issue. That line was commented out from the beginning because I could not find reasons why it was failing back then :)

After reading your post, I realized how simple the issue was and actually conversion was already done in the code here. So after careful analysis I found that converting of '\x' to '%' was incorrectly performed before percent encoding here. Moving conversion down below solved the issue and that test is passing now!

Good catch! Thanks again.
