HTML to read all characters

Hello all,

For our website we are trying to validate HTML and CSS. Once a part is now done a number of times I tick the "against.

It seems to me that this has to do with something in the head, but last week we went php4 to php5 on the server, so whether there could have save me dead.

Maybe someone encountered this problem is.
please reply thank you.

Perhaps because it is something to do with Firefox? Sometimes I also get to see texts in the style:

"The purpose of a ori3433% # Guidance that ...."

Set the appropriate charset in the headers that the server sends to continue. This can be done in several ways:
Setting a charset in Apache by a type of extension to hang.
In the php script header set "header ( 'Content-Type: text / html; charset = utf-8');"

It would also be that you have the burden UTF8 BOM (byte order mark)

Code:

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

as it looks, so that seems good. It is rare that I have not had this and see if 123 is not what the problem is. Take me as I write this html ideas hope good right? or you really ASCI or HTML code?
