Tony Cook provided a patch to resolve Perl #131597: NULL pointer reference in Perl_newRV().


Paul (LeoNerd) Evans asked (lib/ puts references in %^H) for a clarification about %^H which is leading to an improvement in the documentation on the topic.

In new versions you may not use a bitwise operation on characters above 0xFF, but as Graham Knop raises (Behavior of bitwise ops on unencountered wide characters), this violates a possible optimized way to determine a string or number value.

Dave Mitchell shows that open with encoding(UTF-8) could mask an OS error, and asks what we would consider correct behavior here.
