CentOS - Feb 2011 - Unicode in C++

On my CentOS box, in C++ programs, is there a way to print
Unicode characters?

Thanks,
Mike.

if you're running in an xterm that's configured for UTF8, or a ssh 
session to console that's configured for UTF8, then yes.   if you're 
running on a textmode console in VGA mode, probably not.

Why do you want to? And what sort of monitor or client are you using?
Xterm, Putty, NX, SSH,

And what do you mean by "print"? Do you mean send to a printer, or get
them to display correctly on your screen?

The same as on any other Linux box.

Some important tips for beginners:

	*  Don't forget to set your locale appropriately at the beginning of your
program.

	*  Use ONE encoding CONSISTENTLY (utf-8 or utf-16) inside your program, and
trans-code appropriately to/from outer encodings (all such transcoding should
happen at the IO edges). If using UTF-16, make sure you standardise on an byte
order if you are storing the files. UTF-8 doesn't have that issue. US-ASCII
is also UTF-8 (the reverse is not true).

	*  Do not mix data representations. As much as you can, try to stay with either
wide-characters (where every character is represented as a single 32-bit
codepoint) or multi-byte (eg. UTF-8, UTF-16).

		*  Yes, UTF-16 is also a multi-byte character set.

	*  Learn about Unicode Normalisation: it is important when comparing strings.
It is VERY IMPORTANT when comparing strings in a security context.

	*  Software you will want to learn:
		libiconv for transcoding.
		IBM's Components for Unicode (ICU). This is a large suite of commonly
needed Unicode algorithms that libc doesn't have.

Hope it helps,
Cameron
