I am sorry for that. Actually I am not able to proceed. Actually I have to replace all the characters & to & in a file. I should not replace & to & I am facing a problem like this when I use the code: 
#!/usr/bin/perl;
use HTML::Entities;
$to_decode = "TEST&TEST;A&E&an   HTML---   string - < &co
+py; TVS>";
$encoded = encode_entities($to_decode);
print "Encoded data --> $encoded\n\n\n";

[download]
The output looks like this Encoded data --> TEST&TEST;A&E&an   HTML---   string - < © TVS> But the required output is 
TEST&TEST;A&E&an   HTML---   string - < &copy
+; TVS>
