Question with Perl flag "-C"

Question

Why is the "-C" flag unable to enable the "use utf8" pragma?

Answer 1

I assume this is because they control various aspects of coding:

• The - C flag controls the default encoding of input and output streams read or written by the program.
• use utf8 pragma tells the Perl parser if the source code is UTF-8. This can also be detected using the specification in the source file.
