It depends on how the character map is defined. If you don't know how it is defined, the question is useless. If you do know that, you should know how to access the element of the set. So, what is that question about?

sir, what do you mean by "how it is defined"?

In programming there is a term "definition" (as opposed to "declaration"), some piece of code.
But after your clarification it became appear that this is a pretty interesting question which is hard to answer.
It is not "irrespective to font". Unicode defines "code points" of the charactes. Each font define the glyphs for each (roughly speaking, its more complex than that, due to, say, diacritical marks, hinting and a lot more of complex things). Font metadata tells which characters are defined and which are not (by ranges). Which are not are defined are shown as a box.

Now, not every combination of bytes presents a valid character, but this is a matter of UTF; let's consider the code is consistent and correct. But also there are many code point reserved for not yet defined characters...

sorry sir, i have changed the question and made it much more appropriate. Please see if you can answer it.

Are you asking about ASCII and extended ASCII (256 characters from 0x00 to 0xFF)? If so, note that some are not printable (0x00 through 0x1F and DEL).

That makes the question pretty interesting; and the answer is going to be not easy.

The question can be formulated for some font, nothing else. Each font supports certain Unicode subset. You need to learn how to located the font files (a font can be represented by more than one file, as far as I can remember), and then, how to parse those file to get to the metadata describing what subset of code points is supported. Presently, I have no idea where is it documented.

It could be a couple of issues which is what SA was getting at.

See http://stackoverflow.com/questions/420659/unicode-characters-not-showing-in-system-windows-forms-textbox[^]

The textbox does support Unicode but it may be the font you are using or it may be that the font you need is not installed. It may also be how you are loading the text into it.

You are not listening!

What everyone is saying is that what gets displayed is dependent on the font used in the RichTextBox. Go to your application, click on your RichTextBox, and see what the font property is. It us usually Microsoft Sans Serif. But if your system is not setup for the English Code Page, then it may be something else.

There is no font that I know of that can display "every symbol of UNICODE".

"English code page" is totally irrelevant. Code pages are obsolete and used for compatibility (very minimal compatibility). Unicode support does not depend on that.
