How can I convert some html entities to character

[Albert]

How can I convert some html entities (polish) to a character which I can use in a javascript alert?

The entities are:
ń
ę
ń
ą
ż
ś
ć

JavaScript wants all chars as Unicode in \uFFFF form. So say for Polish
middle-soft "L" it will be:

alert("Capital \u0141 and small \u0142");

Your Unicode table to print out and learn by heart :-) is located at:
<http://www.unicode.org/charts/PDF/U0100.pdf>

Also you may use Polish characters as they are. To make your script
page encoding-independent, declare separate charset for the script
itself:

<script type="test/javascript" charset="ISO 8859-2">

You do not have to. You can declare an encoding for the resource that
includes the codes for the referenced characters and use the characters
as they are. Or you can use the character references in an event handler
attribute value, where they are parsed as CDATA already:

onclick="alert('&#x0144;&#x0119;&#x0144;&#x0105;&# x017C;&#x015B;&#x0107;');"
The entities are:

&#x0144;
&#x0119;
&#x0144;
&#x0105;
&#x017C;
&#x015B;
&#x0107;

Those are character references (_not_ entities), and this has been
discussed shortly before. FWIW:

String.prototype.charRefToUnicode = function()
{
return this.replace(
/&#(([0-9]{1,7})|(x[0-9a-f]{1,6}));?/gi,
function(match, p1, p2, p3, offset, s)
{
return String.fromCharCode(p2 || ("0" + p3));
});
}

alert('&#x0144;&#x0119;&#x0144;&#x0105;&#x017C;&#x 015B;&#x0107;'
.charRefToUnicode());
