Do I need NLS?

[blazingice]

This is a very basic question, but I don't seem to get a simple answer. Do I really need NLS enabled when building ports? I tried to read the chapter on "Localization and Internationalization" in the handbook, but I got even more confused. I am using UTF-8 and my login.conf looks like this:

me:\
        :charset=UTF-8:\
        :lang=en_GB.UTF-8:

What will happen if I disable NLS?

I'm not sure but NLS as far as I understand has some connection with fonts? I prefer to always enable it to be sure that I will not have any trouble.
