Percent Encode URL Not Behaving as Before in V. 9

KM9 did make a change to the Percent Encode URL

Adjusted Filter Percent Encode for URL to encode all non-alphanumeric characters.

According to HTML URL Encoding Reference

URL Encoding (Percent Encoding)

URLs can only be sent over the Internet using the ASCII character-set.

Since URLs often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format.

URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.

URLs cannot contain spaces. URL encoding normally replaces a space with a plus (+) sign or with %20.

So the w3schools spec calls for encoding non-ASCII characters.
KM9 spec calls for encoding non-alphanumeric characters.

Here is perhaps a better spec:
Percent-encoding - MDN Web Docs Glossary: Definitions of Web-related terms | MDN

I guess the question is what does @peternlewis mean by "non-alphanumeric characters"? Is that the same as "non-ASCII"?

@andreamocko, IAC, while there has been a change, is KM9 now providing the proper conversion from your POV?
