Re^14: Seeking Perl docs about how UTF8 flag propagates (Terminology)

It doesn't "default to ASCII". It works against decoded text aka string of Unicode Code Points. Always. Even without pragmas. This can be demonstrated using "\N{U+100}" =~ /\w/ (which matches). You need to use /a if to limit it to the ASCII range.

we were talking about encoded text without UTF8 flag Absolutely not. You replied to "Terms describing what a string represents (unrelated to storage format)" (emphasis added).	[reply]
