Compile Bug with special Chars?

h.web

Hi,

i want to use the the rapidXML Library in a project. I get the following issue on parsing special chars:

const char str[] = "deg = °";

prinft(str); //output is 'deg = °'

If i look in the array, i found that the special char '°' is expressed as 0xFFB0! Due to the ASCII Table this should be 0x00B0. Why is the compiler handling this in a different way?

Best regards

Hi George,

the compiler is (TMS320C283456) C2000 TI v6.1.0. with CCS 5.2

Hi Holger,

My guess is: the degree sign is an extend ASCII code, that is, above 127. Using 8 bits this would be a negative number, when the compiler represents it with more bits (16 in this case) it fill the extra bits with ones, the same happens in Visual C++ and also in the windows Calc.

The compiler documentation does not say how extended ASCII chars are handled. So, I entered SDSCM00045178 in the SDOWP system to have this issue addressed. Feel free to follow it with the SDOWP link below in my signature.

Thanks and regards,
