Sorry but only @hwnd's answer worked for me

Solution 1:^[1]

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

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

Solution 2:^[2]

try

&hearts;

NOTE:dont forget to specify

and meta tag too

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

Solution 3:^[3]

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.

Solution 4:^[4]

Another HTML code for the heart sign: ?

&#9829;

see it working in this JSFIDDLE DEMO

Solution 5:^[5]

You can see different Special and Math Symbols in HTML and JavaScript here.

Solution 6:^[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>❤️</p>
