How do I make strings be single byte ASCII and not unicode?

Question

Noticed the system uses unicode to represent strings

const char* text = "Temp is 15 °C";

The ° -char is ASCII B0 but is stored utf-8 two byte C2 B0

 

Answer 1

Actually, º is the ASCII character 167 (see here).

C, C++ stores strings as character arrays. The default interpretation for these strings is ASCII string, not Unicode. For Unicode, various converters should be used.
