change extract_section() to honour POD encoding rather than decode_utf8
replace strip_pod regex implementation with Pod::Simple::Text
reformat for readability - whitespace changes only
add some more test descriptions
gracefully handle unknown =encoding
handle non-ASCII character strings returned by $meta->abstract
declare explicit dependency on Pod::Simple version 3.23
Pod::Simple 2.33 will safely pass through decoded input
move "smart quote" handling to *after* POD rendering
