Treat APRS packets as arrays or buffers of binary bytes. Only after
decoding the APRS packet, some fields such as the comment text and APRS text
message text should be UTF-8 decoded.
message text should be UTF-8 decoded for the purpose of displaying it on a
user interface.
If your programming language or environment supports setting text encoding
for a network socket, do not set UTF-8 encoding for the APRS-IS socket.
Treat it as a binary stream.
When iGating, digipeating or otherwise forwarding packets, forward the
packet data payload as a binary buffer. Do not decode and re-encode as
UTF-8, as it may well break packets which do not happen to be UTF-8.
iGates dropping duplicate packets unnecessarily
