I developed a small html page in region language (Gujarati). But some of nokia phones doesn't support regional language.( Square characters displayed instead of actual word).

Strange thing was that if i wrote something without tag in html, it shows but if i try to display anything withing input tag,it doesn't work at all.

Is the problem related to firmware of phones or opera Mini ?

Some details are as follow:
Nokia 6208 : Works fine with opera mini also.
Sony z550 : Doesn't work
Nokia old phones : Doesn't work with inbuilt as well as opera mini also.

Here is the sample of html page...
