FAF is wherever the instrument approach procedure designer decides, basing the decision on ICAO design procedures etc. Could be G/S intercept, the OM or a DME distance. Marked on Aerad (UK) charts with a cross, although the chart publisher, Aerad, Jepp etc don't decide (or shouldn't decide), it's down to the procedure designer.
