Discussion
Paul (LeoNerd) Evans [24]asked (lib/_charnames.pm 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 [25]raises (Behavior of bitwise ops on
unencountered wide characters), this violates a possible optimized way to
determine a string or number value.
Dave Mitchell [26]shows that open with encoding(UTF-8) could mask an OS
error, and asks what we would consider correct behavior here.
