Is there an equivalent character for the HTML horizontal rule <hr>
or XHTML's <hr/>
tag, that could be used outside of a browser, such as in an executable program, or the JavaScript console. I doubt there is, as we would just use the HTML entity instead.

is the code for a horizontal bar, but not a horizontal line as you want. It will not be possible to create a longer or max-content line with a single Unicode character.
