That's a great example. When ¤t is parsed into a text node it is converted to ¤t.When parsed into an attribute value, it is parsed as ¤t.. If you want ¤t in a text node, you should write ¤t in your markup.. The gory details are in the HTML5 parsing spec - Named Character Reference State
So an actual & got an & escape sequence to render an actual & because early parsers couldn't know if the & was the start of an escape sequence or just a literal &. There are many, many more. So when automated escapers and descapers do their thing with inputs and outputs, they sometimes screw up and will escape **&**amp; as **&**amp ...

"You probably shouldn't actually see & anywhere on the web unless you are working in HTML. & is the code behind the symbol & (an ampersand). There are many of these HTML codes beginning with & and ending with ; that represent special characters that could not otherwise be displayed on a web page.
If you want one to appear in text on a web page you should use the encoded named entity "&"—more technical mumbo-jumbo at w3c.org. While most web browsers will let you get away without encoding them, stuff can get dicey in weird edge cases and fail completely in XML.
Ampersands are escaped like & If I write this HTML as Ampersands are escaped like & it will be displayed as: Ampersands are escaped like & So I actually need to write:
Ampersands are escaped like & which displays correctly as: Ampersands are escaped like &
The HTML and XML encoding for the ampersand character is the entity &. [40] This can create a problem known as delimiter collision when converting text into one of these markup languages. For instance, ...

Authors should use "&" (ASCII decimal 38) instead of "&" to avoid confusion with the beginning of a character reference (entity reference open delimiter). Authors should also use "&" in attribute values since character references are allowed within CDATA attribute values.
I am looking to prevent the symbol "&" from being replaced by "&" within my URL, specifically within JavaScript. Just to expand on this requirement, I am getting my url from an oracle database table, which I then use within Oracle Application Express, to set the src attribute of an iframe to this url.
