URL encoding reserves certain characters for use as delimiters, escapes,
etc. In a URL string, a '%' introduces a hex escape sequence. It doesn't
matter if it's part of the server name, path, file name, whatever. The
syntax of the URL string requires that it be interpreted first as a
three-character hex escape.

If it is part of a URL string, then the URL parser should un-escape it,
meaning that the "%72" in "qwe%72tyuiop..." would become 'H'. I do not
know, off-and, whether the method you referenced in your first e'mail is
part of the URL parser or not. It it is part of the URL handling, then it
would make sense that it un-escapes the string passed into it (on the
assumption that the string was extracted from the URL). If it is not part
of the URL handling, then the string should already be un-escaped before it
is passed into the method.
