I have scanned a sample of the german -burg abbreviature. It is from Diercke Weltatlas, 165. Auflage, Georg Westermann Verlag, Braunschweig 1972, card page 14.
In the north you can find two times the -berg abbreviature in Herrenbg. [Herrenberg] and Brombg. [Bromberg]. SW from Tuebingen you find Rottenb[U]g. [Rottenburg] and south of it there's Weilerb[U]g. [Weilerburg]. Note the fancy >>semi-cyrillic<< shape of the breve between the letters b and g -- it is quite typical for this cartographic font. I don't know what they do with a true breve (like in Romanian) since this atlas transkribes all names into german. The symbol fans may also note the circle with upright flag besides Hohenentringen and Roseck (denoting a castle) and the circle with slanted flag (denoting the ruins of a castle) besides Weilerburg. IMHO, the set of cartographic symbols is another one to be checked against UNicode. --J"org Knappen
