== Naming conventions == 

 Hello, did you actually read WP:BULGARIANNAMES? "The Official Bulgarian method is preferred". The method you are applying is not the official one, for good or bad. The example with Boris Christoff actually remarks that the name is properly romanized as Hristov. 

 I am aware that what you're using is the scientific method, but this is not the common romanization of Bulgarian on Wikipedia. And as you can see, all place names use the official method. 

 Is a book about religion from 1987 seriously your reference that Wikipedia should use the romanization system you like rather than the one the community has agreed about? This cannot be serious.  —   —
