Should work well. Remember that you shouldn't use :utf8 for input. In
the general case, :encoding(UTF-8) is safest.

Can you elaborate more on the subtle difference between:

  binmode(STDIN, ":utf8");
  binmode(STDIN, ":encoding(UTF-8)");

besides that "UTF-8" is narrower than "utf8", as explained in the
man page of "Encode" (section: "UTF-8 vs. utf8").
For output, some codepoints allowed by "utf8" would raise an error in "UTF-8". For input, both get the correct characters, assuming the input bytestream was indeed correct. Or am I missing something?
