Re^4: Problem with escape sequence \x for hex with spaces "\x{ 263A }" (update: codepage)

I think you need to append 'O' for "Output" to the '-C'

(my CMD-terminal has CP 850 so no emojis, sorry А)

C:\tmp>perl -we" binmode STDOUT, ':utf8'; print qq[\x{263A}] "
дџ&#9553;
C:\tmp>perl -CO -wde0
...
main::(-e:1):   0
  DB<1> print "\x{263A}"
дџ&#9553;
  DB<2>

UPDATE (codepage)

А) ah found the way to change the codepage

C:\tmp>CHCP 65001
Aktive Codepage: 65001.

C:\tmp>perl -CO -wde0

... yadda yadda ...

  DB<1> print "\x{263A}"
&#9786;
  DB<2>

PM's codeblocks are limited hereВ, thats what I see ---> ☺ (sic)

update (pre tags)

В) or with <pre><tt> tags instead


C:\tmp>perl -CO -wde0

...

  DB<1> print "\x{263A}"
☺
  DB<2>

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'` [download] For example: $ perlu 'say for $], "\x{263A}", "\x{ 263A }"' 5.036000 ☺ ☺ Update (checking for false positives): $ perl -de1 ...

Re^6: Problem with escape sequence \x for hex with spaces "\x{ 263A }" (debugger's unicode support) by LanX (Saint) on Jun 11, 2022 at 19:40 UTC
> whether p or print is used. good and weird catch. I can reproduce that with -CO on windows `C:\tmp>perl -CO -de0 ... DB<1> p "\x{263A}" Wide character in print at (eval 15)c:/nonBKU/strawberry-perl-5.32.1.1-64bit-portable/perl/lib/perl5db.pl:738 line 2. ... ☺ DB<2> print "\x{263A}" ☺ DB<3> q` I know that `p` is a hardcoded command and the debugger is fiddling with IO to ensure that debugged program and interactions don't mess with each other. Still surprising, hope I find time to look into this. > I don't use the debugger pity, it's pretty close to a REPL, and both python and ruby come with easy REPLs Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l]

Worked a treat on Mac. ~>perl -CO -wde0 # ... main::(-e:1): 0 DB<1> print "\x{263A}" ☺	[reply]
