Concerning 4b9fa9d371 (utf8.[ch]: Add a UNI_DISPLAY_FORMAT_UVX flag for pv_display.) and 190301c569 (sv.c: Make S_not_a_number use UNI_DISPLAY_FORMAT_UVX): I don’t understand what we gain by using \x{ABC} instead of \x{abc}. To my eye, the latter looks better. And I thought perl always used lowercase for hex inside curly braces. E.g.: $ perl5.14.2 -we '() = "\x{abc}" + 1' Argument "\x{abc}" isn't numeric in addition (+) at -e line 1. The commit message for 4b says ‘the core (mainly) uses the uppercase form’, but I haven’t see any examples of the uppercase form in curly braces. For U+FFFF syntax, uppercase is universal, so it makes sense for perl to use that. For \xAB syntax, \xab might look confusing, so uppercase makes sense there. But, again, I believe perl always uses lowercase for \x{abc}, and its less loud than \x{ABC}, so I see no reason to change it. -- Father Chrysostomos --- via perlbug: queue: perl5 status: open https://rt.perl.org:443/rt3/Ticket/Display.html?id=107008Thread Previous | Thread Next
