Thanks for your suggestions.
I tried Convert.ToChar(System.Convert.ToInt32(value, 16)), working well for some unicodes. For ex: 29CA;TRIANGLE WITH DOT ABOVE;Sm;0;ON;;;;;N;;;;;
29CB;TRIANGLE WITH UNDERBAR;Sm;0;ON;;;;;N;;;;; I could see only ⧊.
I need to provide a set of unicode chars to admin in my application, where admin will select some chars as restricted. If any user wants to add new name having restricted chars then warning is displayed "Special character is not allowed as part of name, contact administrator". Now initial filling of unicode chars is required to display in GUI for admin, from sqlserver Database. Since I don’t have unicode DB, I am trying to create a table having unicode characters. I got the hex numbers from http://www.unicode.org/Public/UNIDATA/UnicodeData.txt . These numbers must be converted to unicodes and then inserted in to database, to use them in my application. Below mentioned conversions are not working well for all unicodes to generate.
--> Instead of reading this, converting and then inserting in to database, as James Cloos suggested http://jhcloos.com.nyud.net:8080/utf8s.txt (I could not see many chars for 02E5,02E6,02E7,02E8,02E9,02EA [ ˪]MODIFIER LETTER YIN DEPARTING TONE MARK) if we have any .txt file having unicode characters, then it will be imported directly in to database with out conversion logic.
Please let me know whether requirement is clear.

If you want to do the .NET way, just do:
string value = "3df";
char ch = (char) Convert.ToInt32(value, 16);
Now, because in .NET a char is actually a UTF-16 codepoint, you won't get
anything > U+FFFF. And also, this doesn't take into account unassigned or
invalid codepoints and stuff (unless you're getting your input data from the
Unicode database already)
But my question is, what are you going to do with it then? Most likely you
won't be able to DISPLAY most of those characters, unless you have the
correct fonts installed, so what are you actually trying to DO?
