Hier die ganze Fehlermeldung:
A fatal error occurred when attempting to transcode the character encoding of the document. Either we do not support this character encoding ("default") yet, or you have specified a non-existent character encoding (often a misspelling).
The error was: Encoding not supported.
Wenn ich dann auf der W3C Seite bei encoding von "detect automatically" auf utf-9 umstelle, wird die Seite validiert, allerdings bekomme ich 2 Warnings:
1.Warning Character Encoding Override in effect!
The detected character encoding "default" has been suppressed and "utf-8" used instead.
2.Warning Character Encoding mismatch!
The character encoding specified in the HTTP header (default) is different from the value in the <meta> element (utf-8). I will use the value from the HTTP header (utf-8) for this validation.
