The internal representation of the decoded text could include both.
If some of the bytes in the original byte stream couldn't be decoded
using the specified coding-system, they will be represented as raw
bytes, using 2-byte sequences.  OTOH, Latin characters successfully
decoded into codepoints less than 256 will take 1 byte.

Again, this is just the internal representation of what was decoded.
