Question

I’m getting crazy over these encoding probs…

I use json_decode and json_encode to store and retrieve data. What I did find out is, that json always needs utf-8. No problem there. I give json ‘hellö’ in utf-8, in my DB it looks like hellu00f6. Ok, codepoint. But when I use json_decode, it won’t decode the codepoint back, so I still have hellu00f6.
Also, in php 5.2.13 it seems like there are still no optionial tags in JSON. How can I convert the codepoint caracters back to the correct specialcharacter for display in the browser?

Greetz and thanks

Answer 1

It could be because of the backslash preceding the codepoint in the JSON unicode string: ö is represented \u00f6. When stored in your DB, the DBMS doesn’t knows how to interpret \u00f6 so I guess it reads (and store) it as u00f6.

Are you using an escaping function ?

Try adding a backslash on unicode-escaped chars:

$json = str_replace("\\u", "\\\\u", $json);
