Convert Japanese characters to UTF-8 for php json_encode

I have a Japanese string in my (UTF-8 encoded) database '利用規約' which is passed to php's json_encode function and receive this warning:

PHP Warning: json_encode(): Invalid UTF-8 sequence in argument

Is there a way to convert this to valid UTF-8 in order to avoid this? If the db is utf-8 why would php have a problem with the string?

Update:

Turns out the error was in fact due to a problem with sprintf and multibyte characters a couple lines earlier.

utf8_encode only works with ISO-8859-1 (see language coverage here wikip)

utf8_encode should work for you.

http://www.php.net/manual/en/function.utf8-encode.php

If utf8_encode doesn't work, try mb_convert_encoding:

mb_convert_encoding($string,"UTF-8","auto");
