For that to happen you would pass the `-CIO` flag to perl, which causes STDIN & STDOUT to automatically decode/encode UTF-8. The one-liner as-is outputs "\xef\xbc\x91" (U+FF11 in UTF-8) instead of ASCII 1 because those 3 bytes are what Perl receives on STDIN, and nothing is decoding those to U+FF11. Your s/\d/1/ only works on *digits*, and none of U+00EF, U+00BC, or U+0091 is. So no change happens. -FGThread Previous | Thread Next
