Jun 25, 2018 at 10:53 comment added Taras Banakh @VMrcel You can extend the Cantor starcase function to a continuous function on the closed interval and then you will get a continuous function between closed intervals, for which the quotient pseudometric still is zero. By the way, the quotient space is path-connected in the quotient metric (since it determines the anti-discrete topology). So, maybe some more precise question should be asked (but a good question is a half of an answer).
Jun 25, 2018 at 9:44 comment added VMrcel Thank for the answer ! Indeed it is the same counter-example than in the question I have quoted. However, I have realised that I need to deal with path-connected spaces so that quotient space is path-connected in the quotient pseudo-metric. Is there a known example that does not use the cantor set ?
