(since C++11) The signedness of char depends on the compiler and the target platform: the defaults for ARM and PowerPC are typically unsigned, the defaults for x86 and x64 are typically signed.

Is char in C++ signed or unsigned?
By default, char behaves like an unsigned char . To change this default, you can use the DFTCHAR(*SIGNED|*UNSIGNED) option or the #pragma chars directive. See DFTCHAR(*SIGNED|*UNSIGNED) in the ILE C/C++ Compiler Reference for more information.

What is the value of char in C++?
A signed char can hold a number between -128 and 127. An unsigned char can hold a number between 0 and 255. There are some sequences of characters in C++ that have special meaning. These characters are called escape sequences.
What are the signed char values?
