Well, the subject says everything. I'm using json_encode to convert some UTF8 data to JSON and I need to transfer it to some layer that is currently ASCII-only. So I wonder whether I need to make it UTF-8 aware, or can I leave it as it is.
Looking at JSON rfc, UTF8 is also valid charset in JSON output, although not recommended, i.e. some implemenatations can leave UTF8 data inside. The question is whether PHP's implementation dumps everthing as ASCII or opts to leave something as UTF-8.
