i think that won't be easy:
what do you count as char?
what do you do with images?
does as h1 count more than a simple p?
how does a <br> count?

mmm, I have not to count the html chars or tags, but what I see while I'm typing.
For ex.: I write: CIAO MONDO (THAT IN ENGLISH MEANS "HELLO WORLD")

This is "I write: CIAO MONDO (THAT IN ENGLISH MEANS &quot;HELLO WORLD&quot;)" in HTML.
I don't need to count these chars but the only the number of chars.
So, in this case, the counter is only 57.

I don't know if I explained well, but it's something like the Ms Word counter of words...

I can explain with another example.
I can do the some thing in this way in php:
$testo = "I write: CIAO MONDO (THAT IN ENGLISH MEANS "HELLO WORLD")";

$testo = eregi_replace("&#39;", "'", $testo);
$testo = eregi_replace("&nbsp;"," ", $testo);

while($testo != strip_tags($testo))

{
$testo = strip_tags($testo);

}

$conta = strlen ($testo);

And the counter is $conta...

yes, something like taht would not be too hard, it would just have to be done with javascript

you could write a custom button or a plugin that does that for you...

ok, this is the trouble!
I'm trying to solve that problem and do the plugin (to share after!), but I don't understood how to capture the "htmlarea" textarea.length

with a normal textarea I have simply to write something like:
function donaldduck()
{
var messageField = document.getElementById("id_of_my_textarea_here");
var message = messageField.value;

if (message.length > 500)

{
messageField.value = message.substring(0, 500);
... do this or do that ...
}

}
var tempo = setInterval(donaldduck, 1000);

At present time, I don't really now how to call the "textarea" that xinha create in ram (the one that takes control of the real textarea) from an external xinha plugin, or where put my function in the xinha htmlarea.js (and, again, how to call the "textarea".... var textarea = ..... what?).

thank's again in advice
