Re^7: Default encoding rules leave me puzzled...

What output does that Perl command-line script produce?

C:\>chcp
Active code page: 437

C:\>perl -MScalar::Util=looks_like_number -wE "use utf8; say looks_lik
+e_number('į')? 'yes' : 'no'"
no

C:\>bash
$ perl -MScalar::Util=looks_like_number -wE 'use utf8; say looks_like_
+number("į") ? "yes" : "no"'
Malformed UTF-8 character (1 byte, need 3, after start byte 0xe7) at -
+e line 1.
no
$ exit

By posting a command-line script and then not posting the output it produces, you've made no useful point—at least not one that's immediately understandable.

If you saw `į` in a console set to cp437, you didn't actually have `į` in the script because the code is treated as being UTF-8. Other than properly encoding the `į`, you can address that issue by replacing `į` with `chr(0xE7)`. It will still output `no`.	[reply] [d/l] [select]
