On ASCII hex representation of trademark (™) symbol

[mariot]

Hello guys,

Does anyone know here the ASCII hex representation of the trademark
(™) symbol in mac?

I've tried to open "Special Characters" window on the Edit Menu of the
Finder and I've seen that the trademark (™) symbol only have two hex
representation namely UTF8 and Unicode. No ASCII hex representation
was found.

With this, I cannot find a way to programmatically interpret the
Trademark (™) symbol via ASCII representation.
See my code:

// UTF8 interpretation of trademark (™) symbol
const char utf8test[] = {0xe2, 0x84, 0xa2, 0x00};
NSString *utf8testString = [NSString stringWithCString:utf8test
encoding: NSUTF8StringEncoding];

// ASCII interpretation of trademark (™) symbol
const char asciitest[] = ??? // still pending
NSString *asciitestString = [NSString stringWithCString:asciitest
encoding: NSASCIIStringEncoding];

Please help.

Thanks,

Mario

there *is* no “ascii representation” of the trademark symbol, on the mac or
any other platform. there are only 255 ascii characters, total. that certainly
isn’t enough room for every last oddball character under the sun.

you shouldn’t be using ascii in programming in this day and age, anyway. use
utf-8 or something similar. NSString can deal with character sets
automatically, in most cases.

That symbol is not part of ASCII, so there is no representation. ASCII
on Macs is the same as ASCII everywhere. See
<http://en.wikipedia.org/wiki/Ascii> for more information.

No. There are only 128 ASCII codes. In these 128 codes, only 95 are
used for characters, the 33 others are used for control codes.

Here there are:
