Hi,

If I create an 'old school' SELECT in HTML I can populate its OPTION items with strings that contain superscript characters, e.g., mm

Take a look at what's being rendered in Firebug. I have a feeling you need to use the &xxxx equivalent of the special characters.

Thank you very much Tim,

That's exactly what it was.

If anyone else is interested http://www.intuitive.com/coolweb/entities.html provides a list of HTML Character Entities (e.g., ² for

Guess I should have tested it properly Tim!

Although the drop-down in the Ext.ComboBox renders the Character Entities, e.g., ², correctly, the edit itself doesn't.

Thanks for getting me half-way there, any other ideas?

Not sure what you mean. I added a select handler which alerts me the id and the value.

cbViscosityUnits.on('select', function() {
Ext.MessageBox.alert(this.getValue(), this.getRawValue());
});

Hi Tim,

Sorry, I meant that in the drop-down list itself the entries where being displayed correctly:

I copied your code and put it on a page with an input tag - it appears correctly in the dropdown and in the box after select. Are you using the latest 1.0.1a code?

Well, now I'm confused. I cut and pasted the code from the forum page, so it's in my code without the ampersand coding - e.g just the way it appears on the page here. It works correctly on IE and FF - no squares. I thought this was what you did originally - now I don't know. The other possibility is that it's an encoding issue in the html. I have this in my page.

Thank you Tim, that's exactly what it was: the content-type!!!! Believe me, I will be buying HTML for Dummies tomorrow morning.

I'd tried it every different way with superscripts, then ampersand coding, then ASP pages instead of HTML... never thinking of the meta tags :">

I really appreciate your help - above and beyond =D>
