Open the file with its original encoding for reading, open a new file with utf-8 for writing. Then just read the input line by line and output each line to the new file: 
my $enc = 'cp1252';
open my $IN,  "<:encoding($enc)", 'input.txt'  or die $!;
open my $OUT, '>:utf8',           'output.txt' or die $!;
print $OUT $_ while <$IN>;
close $OUT;
