It doesn't. Document.write itself doesn't interpret anything. It just
writes the contents of the string argument into the document stream so
that the HTML interpreter will process it later.

The argument is a string. If you want to add quotes to a string literal,
you must escape the ones that match the ones around the literal. I.e.,
if you want a string literal to contain:
abc'def'ghi"jkl "mno
you must write either
"abc'def'ghi\"j kl\"mno"
or
'abc\'def\'ghi" jkl"mno'
That is, you escape the quotes that would otherwise end the string.

It has no significance in itself. I looks like something that is used
as part of an URL itself, e.g.

Example Domain

http://www.example.com/request.html?type=foo&Url=dims.html

You can include both : and \ in string literals. If you want to use
them as part of an URL string, you must escape them. In that case,
they do become %3A and %5C. The character escaped as %2F is forward
slash.

My guess is that your document.write is used to write an URL. That URL
contains several arguments after a question mark. Those arguments are
separated by "&"'s, and one of them is called Url. The value of that
argument is an URL which is encoded. Most likely something like
&Url=http%3A%2F %2Fwww.example. com%2Fdims.html
