I encounter this problem, that i can not save a file with extension.php with unicode encoding character.
To be clearer, I am working dream weaver, I use language software to input my own language into html, which worked well, the dreamweaver can save the code correctly and the browser display it correctly.
However, when I type the language in file with php extension. The error message says "the document's current encoding can not correctly save all the characters within the document you may want to change it to UTF-8 or an encoding that support spacial characters in this document
As a result of that, browser screws up my text.
