Tux found that -C3 stopped working properly in 5.22.0​:

  Tux | $ perl -C3 -E'say "\x{2026}"'
  │%ether
  Tux | Wide character in say at -e line 1.

-CIO still works though.

22ff313 is the commit between 5.21.9 and 5.21.10 that broke it​:

  [perl #123814] replace grok_atou with grok_atoUV

Thanks to Tux, LeoNerd, arc, and Zefram for debugging.

(I'll leave it to Zefram to fill in details if he wishes.)

From zefram@fysh.org

The bug introduced by 22ff313 is in Perl_parse_unicode_opts() in
util.c. With the change of calling convention for the number parser, a
separate operation is required to assign the result to the opt variable
from where it will be returned. But the commit erroneously moves this
assignment inside the conditional concerned with having more characters
following the number. It needs to happen conditional only on grok_atoUV
succeeding and the U32 range check.

A side effect of the nature of the bug is that a slight variant of the
-C3 invocation works​:

  $ perl '-C3 ' -E'say "\x{2026}"'

As this is a regression from 5.20, the fix should go into 5.22.1.

From @hvds

Should be fixed now by 89d84ff, apologies for the bug​:

  [perl #125381] fix -Cnn parsing
 
  Commit 22ff313 for [perl #123814] inadvertently changed the logic when
  parsing a numeric parameter to the -C option, such that the successfully
  parsed number was not saved as the option value if it parsed to the end
  of the argument.

I'm not particularly familiar with the -Cx options, someone more familiar may wish to check t/run/switchC.t to see if test coverage needs further improvement.

Assuming this smokes ok I believe it should be good to cherry-pick for 5.22.

I frequently use perl to investigate Unicode code points from the astral
planes. In order to avoid warnings, I am using the -C runtime option. In
version 5.22.0 the numerical arguments are no longer accepted, but the
symbolic arguments still work​:

$ /opt/perl-5.22.0/bin/perl -C7 -le 'print chr(0x1F340)'
Wide character in print at -e line 1.
...

$ /opt/perl-5.22.0/bin/perl -CS -le 'print chr(0x1F340)'
...

Please restore the numerical arguments to the -C option. It works fine
in version 5.20.2​:

$ /opt/perl-5.20.2/bin/perl -C7 -le 'print chr(0x1F340)'

The option actually changes behaviour; it doesn't just turn off warnings.
You can see an obvious difference if you print "\x{ca}" or somesuch.
