in reply to Re^4: Problem with escape sequence \x for hex with spaces "\x{ 263A }" (update: codepage)
in thread Problem with escape sequence \x for hex with spaces "\x{ 263A }"
I don't use the debugger (except in exercises like this) so it's more trial and error than knowledge for me. Anyway, I found the issue actually revolves around whether p or print is used.
$ perl -C -de1 ... DB<1> print "\x{263A}" ☺ DB<2> p "\x{263A}" Wide character ... ... ☺
My guesswork here was based on a long-standing alias of mine:
$ alias perlu alias perlu='perl -Mstrict -Mwarnings -Mautodie=:all -Mutf8 -C -E'
For example:
$ perlu 'say for $], "\x{263A}", "\x{ 263A }"' 5.036000 ☺ ☺
Update (checking for false positives):
$ perl -de1 ... DB<1> print "\x{263A}" Wide character ... ... ☺
$ alias perle alias perle='perl -Mstrict -Mwarnings -Mautodie=:all -MCarp::Always -E +'
$ perle 'say for $], "\x{263A}", "\x{ 263A }"' 5.036000 Wide character in say at -e line 1. ☺ Wide character in say at -e line 1. ☺
