Language tag for German characters?

Hello, I just finished my first bootstrap project with BSS and published it on my webserver. But I've the problem that all German characters are not displayed correctly. I already set those meta tags:

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

Unfortunately there is no change on the German characters (like ä, ü, ö, ß). Is there any way to get this solved? Because when I tested the page locally, everything was okay. Thanks, Enrico

Add this to your .htaccess:

# Use UTF-8 encoding for anything served text/plain or text/html
AddDefaultCharset UTF-8
# Force UTF-8 for a number of file formats
<IfModule mod_mime.c>
AddCharset UTF-8 .atom .css .js .json .rss .vtt .xml

This is a post someone did a few days back that addresses the way to add the language code to your head area. Hope this helps:
