Doubtful.

First of all, it is not a filename.  Non-ASCII characters have to be escaped 
in the _URIs_ which are required by the CSS “url(…)” function.

Also, invalid UTF-8 sequences in text declared to be ISO-8859-x-encoded 
could only be those for ISO-8859-x characters found in the Unicode character 
set with a Unicode code point beyond U+007F (which are not used in basic 
JSON syntax, so could not produce syntax errors), and would be replaced with 
U+FFFD.  That is, the HTTP request later would fail (404), but the JSON 
parsing would not.

Also, _JSON_ is not a “message”, but a data-interchange format.

<http://json.org/>

(This part of the discussion is actually on-topic for a change, because PHP 
supports JSON decoding and encoding; see <http://php.net/json>.)

Apropos “invalid”, the address part of the From header field value of your 
postings is, and it is also anti-social.
