Pronunciation of FYROM

[Jim Rader]

Does anyone on the list know if there is a conventional pronunciation
of this initialism in English?  Is it pronounced as an acronym,
something like "FI-rome" (FI rhyming with "die") or is it just
pronounced as a sequence of letters, i.e., "f-y-r-o-m."  I would be
grateful for any personal knowledge, or leads to personal knowledge,
from people familiar with the modern Macedonian political situation.
