+# BGN/PCGN 1952 System
+#
+# This system was adopted by the BGN in 1949 and by the PCGN in 1952.
+# It reflects the much simplified Bulgarian orthography as officially
+# revised in February 1945. The Bulgarian alphabet contains all of
+# the characters present in the Russian alphabet with the exception
+# of Ёё, Ыы, and Ээ. Two obsolete letters Ѫѫ and Ѣѣ are also given.
+#
+# The Bulgarian Alphabet as defined by the BGN (Page 15):
