This PR adds configurable UTF-8 handling for APRS message traffic to
improve interoperability with modern clients such as APRSdroid.
It introduces a global config option that controls both:
- incoming message normalization for display in legacy Motif/Latin-1
UI paths
and
- outgoing message encoding so transmitted payloads can be UTF-8.
What changed:
- Added global runtime/config variable traffic_utf8_enabled.
- Persisted setting in xastir.cnf as TRAFFIC_UTF8 (load/save).
- Gated incoming conversion in message ingest/display code paths.
- Gated outgoing conversion in message output path.
- Updated unit-test stubs to include the new global symbol used by db.c
test links.
Behavior:
TRAFFIC_UTF8=1 (default):
Incoming: normalize UTF-8 message text for Latin-1 UI display.
Outgoing: encode Latin-1 UI input to UTF-8 before transmit.
TRAFFIC_UTF8=0:
Preserve legacy byte behavior (no UTF-8 parse/send conversions).
Closes #380
