Add Unicode Meta tag to XPages for Polish Characters

I have the need to support different languages in my xpages. I have been informed that the Polish language have special characters which is part of the unicode character set. I have read that I need to add the following to my xpages to support Polish

<meta http-equiv="content-type" content="text/html;charset=utf-8" />  

My question is if it is safe to add this meta tag to my xpages without breaking my xpages when using other languages. or should this Meta tag only be applied when using the polish language?
