fix CLDR TL;DR issues from PR #26

◦ remove pod =encoding
◦ add shebang for perl syntax highlighting
◦ replace example using U+201E DOUBLE LOW-9 QUOTATION MARK to avoid Chrome bug

plus:
◦ explicitly use modules in code examples
◦ minor text changes
output looks better without C<>

otherwise you can't tell the difference between U+201C LEFT DOUBLE QUOTATION MARK
and U+201D RIGHT DOUBLE QUOTATION MARK
