Aah yes - 1-2 exceptions. But as you say, they are usually sacrificed. :)

Id term it a bit different - they are "unusual" but certainly not difficult
to read in any way an in fact people are used to such here in the railway
stations and airports. In fact many of them have stuff from 1960's or prior
with missing dots and other - so it becomes even more fun. :)
