I've found the solution:
This (Persian Language) works for all Browsers (Internet Explorer, Firefox, Google Chrome, ...)
Edit
main_post_form.html and paste this script somewhere above
<!--Persian Language Script-->
<script type="text/javascript">
var
arabic =' !"#$%،گ)(×+و-./0123456789:ك,=.؟@ِذژىُيلآ÷ـ،/'د×؛َءٍ،'{ًْإ~جپچ^_پشذزیثبلاهتنمئدخحضقسفعرصطغظ<|>ّ';
function keyenter(ev){
var
acode = window.event ? window.event.keyCode : ev.charCode;
if (acode>31 && acode<128){
if (ev.target){
ev.target.value +=
String.fromCharCode(arabic.charCodeAt(acode-32));
ev.preventDefault();
}
else{
window.event.keyCode = arabic.charCodeAt(acode-32);
}
}
}
</script>
<!--/Persian Language Script-->
just put this
onkeypress="keyenter(event)" like this:
<textarea name="postText" id="postText" cols="38" rows="10" class="textForm postingForm" tabindex="2" onkeypress="keyenter(event)">{$postText}</textarea>
