-----------^^^^^^^-------- Here, may be you are right, I don't know that.
I think the string is useless to store into a compiled file.
I am not saying this:

It's tricky. I am really not meaning this. :p
May be for the compiler, they all contenting a string.
Try my attached file to understand what I mean. Compile it to an object file or
a executable file, and then open it with an editor, you can find two "AElig".
And the 2nd is useless.
As I know very little about the compiler. I just present you the fact.
May be implement this "skip the useless string" could be hard, or need many
codes. I am learning.
