This patch fixes handling of invalid unicode when using suspendable ports.
Reported upstream at https://debbugs.gnu.org/cgi/bugreport.cgi?bug=62290 and
patch merged as cba2e7e3fec3c781230570f5d1ef070625eeeda8.
As the build coordinator agents use suspendable ports, this will fix issues
with building things where the log output contains invalid unicode.
