Issue #14096 has been reported by headius (Charles Nutter).
----------------------------------------
Bug #14096: Psych allows invalid single quote escape character
https://bugs.ruby-lang.org/issues/14096
* Author: headius (Charles Nutter)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: 2.4.1
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
In https://github.com/jruby/jruby/issues/4847 (and previously in https://github.com/jruby/jruby/issues/2199) we have had users report that escaped single quotes within a YAML string do not parse in JRuby, although they parse in MRI.
According to the YAML specs (both 1.1 and 1.2), `\\'` is *not* a valid escape character. The YAML library we use, SnakeYAML, has pushed back on adding it since it is not part of the spec.
Why does MRI parse this invalid YAML?
```yaml
