In Germany? Never heard of anything like that! Between the French border and EDSB and between EDSB and EDNY there is no airspace restriction at all. Apart from ED-R 9 that covers the whole of Germany and starts at 10.000 ft MSL, above which a clearance is required for VFR flying (which is near impossible to get).
If I remember well Germany has those mill. low flying areas 1 to .. as shown on the Jeppessen maps.
And some(most) fields have German R/T only. Most of the time one get an answer in English but do not count on that.
