एशियाई अक्षर <optgroup> लेबल पर नहीं दिख रहे हैं

I have a very simple test123.aspx page in Visual Studio 2010 (C#), with this code on it:

The problem is that when I bring up the page in any browser (chrome or firefox or IE), the 2nd and 3rd < optgroup > labels do NOT appear in the selector, while the first < optgroup > does appear. All three < option > values appear. When I view source on the page, I see the exact code above.

Not sure how relevant it is, but I do have these two tags in the at the top:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />

Anyone know how I can make the 2nd and 3rd labels appear in the browser?
