well, i have a letter that i wrote as label of text box and its very fine in IE, now i type same letter in text box but it appear as rectangle? And when i save the data submitted from form into database and retrieve it back its appearing very fine as label(though it was displayed as rectangle ). Problem is just when i type in text box? As you said this seems to be problem with font but why it appears correct as label then?
Also i am using MS San Sarif which is mentioned on XP site to support Arabic/Urdu characters.

Glyphs appearing as rectangles usually means that the font being used to display the document does not contain the glyphs to display those characters (- or sometimes that there are errors in the glyph outlines which can prevent them from being properly rendered on some systems).
This problem will often occur if the character set being used to display the web page is wrong (misinterpreted by the browser) - since the font may not contain glyphs for *that* character set. When a glyph outline for a particular character is not present in a font then the "default glyph" defined in that font (usually an empty rectangle) is displayed for that character.
An OpenType font should contain glyphs for the nominal forms of all the Unicode characters it supports - and these nominal glyph forms should be mapped directly to the corresponding Unicode codepoints. Thus, even without Uniscribe, the nominal glyphs for those characters should be displayed by the basic font rendering system - though you won't get any of the contextual shaping relying on OpenType lookups which under Windows are handled by Uniscribe.
