What is the range of 866 encoding in c++, 1251 from 0 to 255, and 866?

Answer 1

too - from 0 to 255
all non-unicode - byte (if suddenly not all, then this is already exotic). the only difference is which character (image) is meant for a specific value

keep in mind that in both cases the "second" half of the range (128-255) is given, since the "first" (0-127) is identical to ASCCII
