The UK emergency number is 999.

In most of Europe it is 112, and that will probably work here too. It's probably the one to memorise if you are travelling in Europe and want a single number, but few British people would use it here because 999 is what we trust.

Wikipedia says that 119 is the emergency number for Korea, Japan and some other places (unless you want the police, in which case it is 110). In France it would get you to a child protection line.
