Hi Niels, while hunting down the fallout of https://github.com/Perl-Critic/Perl-Critic/issues/925 in Lintian's test suite, I stumbled upon this confusing line of code:
98: join(' |̈́ ', $one->name, @provides_one));
[…]
108: join(' | ', $two->name, @provides_two));
Note that the joining string of the first join() contains the Unicode
character U+0334 "COMBINING TILDE OVERLAY" after the pipe.
Via "git blame" I traced the introduction of that character (and
actually both these lines) to this commit from 2012 (!):
commit 1d64fd8a88d18511d45af4e8fd64f4d4f38b43d3

I will very likely remove that unexpected Unicode character because
— especially with the second line not having it — it just doesn't seem
to make any sense.
Nevertheless I would like to know if this was an accident which has
been undetected for 10 years (and one month :-) or if this COMBINING
TILDE OVERLAY character was added was on purpose. (In case of the
latter, I'd be very curious about that purpose. :-)
Kind regards, Axel
