About
The charset declaration directive, specified via an 
HTML meta tag or HTTP headers, defines the character encoding used to interpret text in a web document.
If not explicitly declared, browsers attempt to detect the encoding or fall back to defaults, which can lead to incorrect rendering or even security issues in some cases.
