Printing unicode character

[Manoj Kumar Jain]

Hi all,

Just to see some Unicode character I wrote a small code to print the Unicode character from 128 to 255.

for (int ch = 128; ch < 256; ch++) {
				char charValue = (char) ch;
				System.out.print(ch);
				System.out.println(" " + charValue);
				
			}

when I run the code the output was as below

128 ?
129 ?
130 ?
131 ?
132 ?
133 ?
134 ?
135 ?
136 ?

it prints "?" up to 159, prints space for 160 and after that it prints some symbol.
So I am wondering why its printing "?" for many of the values. do we need to install fonts in my system to get these symbols printed ?

Not sure, but it's unlikely that you'll get the output on a standard console or command line program (although it may be possible in some Unix terminal emulators).

Have you tried displaying via a Java Swing Component, such as a JTextField? I'm no GUI expert, but I suspect it'd be much more likely to handle "abnormal" characters than a standard 'term'-type display.

No Winston, There is no GUI component. I am running this piece of code in eclipse with windows environment, I can see this output on the eclipse console.
however now I tried to run it one the command prompt, and output was the same.

[edit]
However when I look for the values of these Unicode 128-159 it says that it's a <control> kind of but have some symbol to represent.
below is the link:

So is that the reason that these are not being printed ? not sure..

Are you sure that the console output in Eclipse or on the command prompt is using a font that contains the Unicode characters that you want to display? Not all fonts (especially the default font used for the command prompt window) contain all Unicode characters, and you'll see question marks for missing characters.
