Is there any way in C to print ® ?

[g.kanaka.raju]

Hi,

I'm looking for a way to print ® in a C program. Could any of you
help me out?

Regards,
Raju

putchar('®');

Though this is not strictly conforming since ® is not a member of the
basic
execution character set.

Under C99, you can try...

putchar('\u00AE ');

You could do...

printf("®");

....and pipe your output through a html browser.

Lastly, just do printf("(R)");

try this:
/*CODE BEGINS*/
putchar(174);
/*CODE ENDS*/

it will only work however if your system character set supports that
character.

What's the legal status of (R)? I know that (c) doesn't have any legal
status, though it hardly matters in jurisdictions where copyright is
automatic.

Being more generic, you can lookup the character/symbol that you want
to print in a ascii table. 174 is ascii for (R).

Wrong. ASCII only extends from codepoint 0 through to codepoint 127. Any
characterset that has other codepoints /is not ASCII/.

A more definitive source would be the ISO, ANSI or ECMA standards
documents. Of the three, the ECMA documents are the only 'free' ones
around. Check
http://www.ecma-international.org/pu...T/Ecma-006.pdf
and
http://www.ecma-international.org/pu...t/ECMA-048.pdf

Alternatively, you can take a look at the ISO/IEC JTC 1/SC 2 definition
of ASCII at http://anubis.dkuug.dk/i18n/charmaps/ASCII

Last I checked ASCII used seven bits to represent character values and
there are not 174 different possible encodings with 7 bits. Certain
extended codesets may define larger values using more bits but they are
not ASCII.

This is not true, but is a common misconception. ASCII has values in
the range [0, 127]. Any character value that is greater than 127 is
*not* ASCII.

Yeah, this should work...

#include <wchar.h>
#include <locale.h>

int main(void)
{
setlocale(LC_CT YPE, "");
putwchar(L'\u00 AE');
putwchar(L'\n') ;
return 0;
}

Here is what happens when I run it on my system:

[sbiber@eagle c]$ echo $LANG
en_AU.UTF-8

This means that my system locale is set to Australian English, and the
execution character set is UTF-8.

[sbiber@eagle c]$ c99 -pedantic regtr.c -o regtr

It compiles cleanly as a C99 program.

[sbiber@eagle c]$ ./regtr
®

When run in the usual way, it outputs a registered trademark symbol in
the locale's character set, UTF-8.

[sbiber@eagle c]$ LANG=C ./regtr
(R)

When run in the C locale, it outputs the best-possible ASCII
representation of the character, which is the three characters '(', 'R',
')'.

[sbiber@eagle c]$ LANG=en_AU.ISO-8859-1 ./regtr | iconv -f ISO-8859-1
®

When run in the locale corresponding to Australian English in the
ISO-8859-1 character set, it outputs the registered trademark symbol in
that character set, which I then send to the 'iconv' command to convert
it from that character set back into the system default, UTF-8.

This does NOT work even on some systems where '®' is a member of the
execution character set, because the character '®' may be a multi-byte
character. To be specific, on this Linux machine it consists of the two
bytes 0xC2 and 0xAE:

[sbiber@eagle c]$ echo -n ® | od -t x1
0000000 c2 ae
0000002
Under C99, you can try...

putchar('\u00AE ');

This has the same problem, as \u00AE may be a multi-byte character. One
correct solution is to put it in a string.

For example, puts("®") will always work so long as the character exists
in the source and execution character sets, even if it happens to take
more than one byte.

If you can't guarantee that the source character set contains the
character, you can use a universal character sequence, ie.
puts("\u00AE"). This will still fail if the execution character set does
not contain that character, of course.

#include <stdio.h>
#include <locale.h>

int main(void)
{
setlocale(LC_CT YPE, "");
puts("This is using a literal character: ®");
puts("This is using a universal character sequence: \u00AE");
return 0;
}

[sbiber@eagle c]$ c99 -pedantic regtr.c -o regtr
[sbiber@eagle c]$ ./regtr
This is using a literal character: ®
This is using a universal character sequence: ®
