Issue #14110 has been updated by duerst (Martin Drst).

Status changed from Open to Closed

My understanding is that bugs get backported, but features don't.

While I think allowing \u{} can be convenient in some cases, I don't think it was part of the original design, and so I would think about it as a feature.

Bug #14110: Ruby 2.5.0.dev (from trunk) still doesn't support zero unicode codepoints

Hi,

This commit - https://github.com/ruby/ruby/commit/7e8b910 - according to its commit message should allow zero unicode codepoints, i.e.

~~~
$ cat test.rb
p "\u{}"

$ ./ruby -v
ruby 2.5.0dev (2017-11-14 trunk 60757) [x86_64-darwin17]

$ ./ruby test.rb
test.rb:1: invalid Unicode escape
p "\u{}"
      ^
~~~

Shouldn't it be supported now? Because the test that was removed (that zero codepoints are not supported) is still passing.
Thanks.
