Good afternoon!
There is a binary file in ansi encoding, I copy it to a file with utf-8 encoding, the first file is 7168 bytes in size, and the second (where I copied the text) becomes 7,736 bytes in size. The same quantity and order gave for some reason a different size. Please explain why

Binary? Recode? Don't expect it to remain binary after that.

In UTF-8, characters corresponding to ASCII are encoded in one octet, but characters of other code pages are encoded in a different number of octets (from 2 to 4x at present), for example, Cyrillic characters or characters specific to European languages are encoded in 2 octets.
In ANSI encodings, characters are always encoded as one octet, and an ANSI encoding can contain more than just ASCII characters.
