 i am having a file in which i have statement

$ret_val = system("perl $ENV{SOURCE_ROOT}/scripts/Test_script.pl");

and i want to make a substitution in which i want to remove occurence of perl from this line. i tried this by using 
file handle for that file and doing following substitution

$line =~ s|\perl \$ENV{SOURCE_ROOT}/scripts/Test_script.pl|\$ENV{SOURC

but i am getting following error message

Can't find unicode character property definition via main->e or e.pl a unicode/Is/e.pl line 41

i dont know why this is coming . how can this be removed so that my substituton is done correctly
