Detected locale "C" with character encoding "ANSI_X3.4-1968", which is not UTF-8.
Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead.
If this causes problems, reconfigure your locale. See the locale(1) manual
for more information.

Signing: CLI flags above win per field over the matching env vars.
Passwords must be hvigor-encrypted blobs. If any signing input is set,
all six required values must be present, or the HAP is left unsigned.
