Language file in utf-8 and header problem

[eluser]Unknown[/eluser]
Hi!

I have this problem when I created language file and make it utf-8 encoding (as I have on my web) it gives me $this:

A PHP Error was encountered

Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at C:\Program Files\XAMPP\xampp\htdocs\noted\application\language\polish\core_lang.php:1)

Filename: libraries/Session.php

Line Number: 662

When I change encoding to ANSI it goes clear and well (but i haven't special language signs)... how can I make my file utf-8 without error?

thank you in advise for an answare.

regards,
newicz

What editor do you use to edit the php files? Make sure the files aren't saved with a UTF-8 BOM header...
