-# Program for testing regular expressions with perl to check that PCRE handles
-# them the same. This is the version that supports /8 for UTF-8 testing. As it
-# stands, it requires at least Perl 5.8 for UTF-8 support. However, it needs to
-# have "use utf8" at the start for running the UTF-8 tests, but *not* for the
-# other tests. The only way I've found for doing this is to cat this line in
-# explicitly in the RunPerlTest script.
-
-# use locale;  # With this included, \x0b matches \s!
-
-# Function for turning a string into a string of printing chars. There are
-# currently problems with UTF-8 strings; this fudges round them.
