wpml_encode_custom_field

description:

Custom fields can be encoded in a format that WPML does not understand. Those fields have to be decoded and encoded before WPML can translate them. To achieve this, the wpml_decode_custom_field and wpml_encode_custom_field filters must be used. These filters can be used if there is additional custom encoding besides the ones already handled by WPML.
