So, as far as I can gather, characters in the upper latin-1 range (i.e. characters 127-255) are lowercased by lowercasing operations iff:

- The unicode flag is on on the string


- The "unicode_strings" feature is in lexical scope (which it is if you use -E)

Just when I thought I knew everything there was to know about unicode and Perl, another random bit of knowledge comes along.
