Sorry but only @hwnd's answer worked for me

Answer 1

The term you're looking for is "entity." There are only a few named entities in HTML, but you can specify any character by its unicode ID:

♥ will show up as: ♥

Answer 2

You want to actually use the Unicode escape sequence \u2665 in your array for replacement.

var key_stroke = { 'heart': Array('\u2665') };

Answer 3

try

NOTE:dont forget to specify

<meta http-equiv="content-type" content="text/html; charset=UTF-8">

and meta tag too

<meta http-equiv="Content-Type">

Answer 4

The black heart character has the unicode code 2665. In HTML unicode symbols can be output in the format prefix code suffix where prefix is always &#x and suffix is always ;. The character you want to output has the code 2665, so it can be done like this:

<p>character - &#x2665;</p>

The output is:

character - ♥

Because you are adding the character to a JavaScript array object (as literal), you need to use the unicode character representation (as @hwnd suggested) in JavaScript, by preceding the unicode character by \u (followed by the character code):

var a = Array('\u2665');
$('#panel').text(a[0]);

A reference to the unicode table containing all character codes: unicode character table.

Answer 5

Another HTML code for the heart sign: ♥

Answer 6

Red Heart Symbol Hex Code

If you want to use red heart variant you have to use two unicodes:
U+2764 - stands for heavy black heart
U+FE0F - is a variation selector

To insert ❤️ symbol in html type it's hexcode <p>&#x2764;&#xFE0F;</p>
