PHP Cron Job json_encode error
===

I have a PHP file that's running a simple check for currency conversion. It works perfectly when I run it through my browser but my goal is to build a cron.  When I run the script via SSH:

    php /path/to/file.php

I get the following:

    PHP Warning:  json_encode(): Invalid UTF-8 sequence in argument in /path/to/file.php on line 36

Where line 36 is:

    fwrite($fh, json_encode($conversions));

...where $conversions is a simple single-dimension array
