I have recently noticed when I copied web address which was in Japanese after copying on a note pad or even in the MS outlook email it turned like this %E3%82%B9%E3%. Before it was copied in the same language such as English or Japanese. When I look at the address in the browser it is in Japanese but if I copy and paste it turn in to %E3%82%B9%E3%. What could be the cause? Is it normal. Any guidance/help will be much appreciated.

Thank you in advance.

This is absolutely normal. In the actual URL, forbidden characters are stored (proper term escaped), as %##, where ## is the hexadecimal ASCII code, for instance space is %20. Multiple (usually 2-3) consequent codes are used to encode Unicode characters. Firefox and most major browsers will translate these into text whenever possible for your convenience. As not all browsers currently support this translation, they may act strange if you try to open a URL containing these characters. For instance, a space may indicate that the input text is actually a search query. URL parsing may also malfunction if you use special characters, so posting such an encoded URL in a forum, such as " that has spaces" will result in only the first part of the URL (before the first space) being recognised. If you want to use Kanji or other characters in hyperlinks, use custom hyperlink text where available and rewrite the characters in there. There is an online converter for this as well. Example:メインページ Actually refers to:
