'taint' mode When "use re 'taint'" is in effect, and a tainted string is the target of a regexp, the regexp memories (or values returned by the m// operator in list context) are tainted. This feature is useful when regexp operations on tainted data a...

utf8 - Perl pragma to enable/disable UTF-8 (or UTF-EBCDIC) in source code River stage five • 10313 direct dependents • 30438 total dependents

The "use utf8" pragma tells the Perl parser to allow UTF-8 in the program text in the current lexical scope. The "no utf8" pragma tells Perl to switch back to treating the source text as literal bytes in the current lexical scope. (On EBCDIC platform...
