c++ - Convert wchar_t to char

Question

asked Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

I was wondering is it safe to do so?

wchar_t wide = /* something */;
assert(wide >= 0 && wide < 256 &&);
char myChar = static_cast<char>(wide);

If I am pretty sure the wide char will fall within ASCII range.
