C programs represent strings within messages as byte arrays. Before sending an outbound message, EMS programs translate strings to their byte representation using an encoding, which the program specifies. Conversely, when EMS programs receive inbound messages, they reconstruct strings from byte arrays using the same encoding.
When a program specifies an encoding, it applies to all strings in message bodies (names and values), and properties (names and values). It does
not apply to header names nor values. The function
tibemsBytesMsg_WriteUTF always uses UTF-8 as its encoding.
Connection URLs are limited to a length of 1000 characters. Note that this limit pertains to the C client library, as well as the administration tool and the
factories.conf configuration file.
In EBCDIC environments, the EMS client library automatically converts message strings. To client programs, all strings appear in the host code page. On the network, all strings appear in the network host page. For details, see
tibems_SetCodePages() on page 537.
