I have an array which one of the keys contains some HTML code. I am json_encoding this array for returning. I have recently noticed that json_encode() returns ‘null’ if the html contains special characters (ie: A méh virága).
How can I get json_encode() not to return ‘null’ if special accented characters are available?
json_encode()assumes that text is in UTF-8 encoding. If the input looks like malformed UTF-8, it returnsnull. The only way to getjson_encode()to work is to give it input in UTF-8 (which you should probably be using anyway).And, as Zathrus Writer says in a comment, the actual PHP source code itself should probably also be in UTF-8 encoding, to prevent subtle bugs.
