display problem of UTF-8 characters

8,658 Recognized Expert Moderator Expert

Hi,

I want to display some Unicode Entities (arond U+2650, some graphical symbols) but I can’t get them to display in the browser (tested FF, Safari)

what I have:
.html file (utf-8 encoded)
.js file (utf-8 encoded)

insert:

Expand|Select|Wrap|Line Numbers

 obj.symbol = "&#9820;";

// somewhere later in the code
 element.innerHTML = obj.symbol;
 

now what happens is that the symbol is converted into an Unicode char (I can text select one single char) and inserted into the HTML, but there is no visibility (besides that I can select it...).

ex. "♜"

strangely enough, if I select and copy-paste the text into my editor, I get the character as if nothing had happened. ah, yes, and of course the ACSII and ISO range values all work (e.g. 252).

if I use

Expand|Select|Wrap|Line Numbers

 obj.symbol = "&amp;#9820";

// somewhere later in the code
 element.innerHTML = obj.symbol;
 

I get displayed "♜" i.e. the symbol string is not converted at all.

there’s (possibly) one kind of solution, though. MDC has a String.fromCharCode() fix for UTF-16. it could work for multibytes as well (if you change the base values … which I don’t know).

can anyone help me fix that problem?

thanks

just tested the following in 3.5.5pre on ubuntu ... which worked and displayed the symbol seamlessly:

Expand|Select|Wrap|Line Numbers

 <html>

<head>

<script type="text/javascript">

function setSymbol(val, nodeId) {

    var node = document.getElementById(nodeId);

    node.innerHTML = val;

}

</script>

<body>

<div id="foo"></div>
 
<input type="button" value="setSymbol" onclick="setSymbol('&#9820', 'foo')"/>
 
</body>

</html>

may be i didn't get the problem quite well?

kind regards

didn’t work at first either, until I changed to some rather unusual font* (I already tried Georgia, Verdana, Tahoma, … with no luck)

* - MS Gothic

@gits
strange, but yes. seems that the “normal” webfonts do not have glyphs in that specific Unicode range.
