This apparently causes problems on at least some database systems (I didn't notice, but@vincenttouzet did). I also read that, for example, SQS doesn't like null characters. And, in general, because we're sending this data over a transport, `base64_encoding` data is pretty standard.Does anyone see any downsides?Cheers!Commits-------fe7ad81 base64_encoding inside PhpSerializer to avoid null characters
