Bug #14488
closedUnicode characters prevent [[:punct:]] character class from matching certain characters in subsequent matches
Description
In 2.3.5, [[:punct:]]
doesn't match +
. In 2.5.0, it does. In 2.4.3, it matches, but not after you match against a string containing one or more unicode characters. I would expect 2.4.3 to have the behavior of 2.5.0.
puts RUBY_VERSION
p %w[+ é +].grep(/[[:punct:]]/)
2.3.5
[]
2.4.3
["+"]
2.5.0
["+", "+"]
One of the commenters here noticed that this behavior may be related to this issue. It seems that `[$+<=>^|~]`` are affected by the bug, but other punctuation characters aren't (though I tested only a handful of them).
