I admit I'm lost in the thread and I'm not really sure about what the
problem is but JSON _has_ to be Unicode. It's by design:

«A string is a sequence of zero or more Unicode characters, wrapped in
double quotes, using backslash escapes.»

http://www.json.org/

And, as already mentioned, json_encode() needs UTF-8 input data:

http://php.net/json_encode

If you need ISO-8859-15 at either end, you need to make a conversion
from ISO-8859-15 to UTF-8 *before* calling json_encode() and/or a
conversion from UTF-8 to ISO-8859-15 *after* json_decode().

In any case, every time I hear the expression "odd characters" I suspect
that the character set of data is simply unknown. The first step is to
learn which one it is.
