Goal

Ensure that deployment failure logs contain legible Unicode characters when diagnosing issues in Dyalog APL.

Constraint

The documentation does not specify whether ⎕LOGFILE writes UTF‑8 independently of the host console code page or inherits it, leaving uncertainty about how non‑ASCII error messages are recorded.

Questions

Does ⎕LOGFILE always encode log entries in UTF‑8 regardless of the console code page?
Can the encoding be overridden via a system variable or option?
If the console code page differs from UTF‑8, will already‑logged entries appear garbled or can they be corrected?
