Bug #124810 for Eval-WithLexicals: eval sometimes fails for UTF8 code in arguments

Environment: Observed in Eval::WithLexicalsour $VERSION = '1.003006'; # v1.3.6 perl -vv5.26.1 Fedora Linux 4.15.8-300.fc27.i686 echo $LANG en_GB.utf8 --------------------------------------------------------------------------------Bug description: The attached Perl file evalutf8.pl calls Eval::WithLexicals' eval function on a code string containing three German umlaut characters ü and ä: my $slogan = "Schüssel für Säue."; This call results in an error: Unmatched right curly bracket at (eval) line 10, at end of line syntax error at (eval) line 10, near "}" despite no curly bracket being contained in the code string. The error goes away if any one of the three umlaut characters is deleted from the code string so that only two umlaut characters remain. Perl's built-in eval function works fine with the code string despite three umlaut characters.
