Similarly I learnt the German symbols for logic gates

looks like what you'd expect, the OR gate looks like an AND gate -- it
has a straight back -- but the input lines are continuted across the
symbol to the curved face), but now use the normal US sysmbols when I'm
drawing schematis, since everybody else does. I can still read a
scehamtic using the German symbols, of
course (nad often have to ;-)).
I'dve thought that the EU would have changed over to those dreadful
IEC symbols by now (BS/EU EN 60617-12:1999). I stumble through those
with my nose held. It's like reading a musical score that's been
reduced to text with note names and durations. There's no visual
"flow".
