Webpage won't show certain characters

I'm noticing that in places where our site uses special characters on a webpage, such as ¡ or ¿ or even "special quotes" (like MS-word) it displays this funky � character

Is there something I can to do fix this? Is this a charset thing?

I know I could use html entities, such as

¡

But, I wanted to see if there was something else to address this since I notice some other sites don't need to use 开发者_C百科the special code.

Thanks

did you try to use the following meta tag?

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