Re: why no default unicode?

If add an environment variable: set PERL5OPT=-CSD Perl will default STDIN/STDOUT/STDERR & all opens to use UTF-8 by default. Which may or may not be what you want.

See perlrun -C & Perlrun Environment variables for details.

Well, I'd prefer it to use UTF-8 for the Term if there term is setup to use UTF-8 (i.e. as expressed by local). For files, it should probably default to binary unless told otherwise. Since all my terms are UTF-8, is how about a way to tell it to use UTF-8 on 'tty' devices, but default to binary on files? Too much intelligence built into the startup code, probably eh?... Either that, OR..."auto-switch": if detect widechar on output, then convert to UTF-8 bytes... That would be the most helpful -- since it knows I'm trying to output a wide-char, so it should (IMO) try to do the best it can and assume a UTF-8 output device... What would be the 'downsides' of that approach? (I.e. instead of the current approach of putting out a warning)...	[reply]

Read the linked documentation. If you don't want open to default to utf-8, then set `PERL5OPT='-CS'` As for auto-detecting. There is no way for perl (or any other language) to determine the difference between an input file containing utf-8, and an input file containing arbitrary binary. Indeed, there is no way to distinguish between utf-8 and utf-2 or utf-32 or arbitrary binary. In this respect the entire unicode standard is terminally broken.
