that means it interprets input as UTF-8 data and parses it to perl character string

Question is - why?
In documentation I see:
On parsing (both for getline () and parse ()), if the source is marked being UTF8, then all fields that are marked binary will also be be marked UTF8.

But I did not "mark" anything as UTF-8. And what is "marking" here?

How to control this behaviour - when to parse as binary data and when as character strings?

Note that I don't want to use Text::CSV::Encoded, as it's broken now
