The Germans use H for B (and B for B-flat), that should help.
- Thus Johann Sebastian Bach managed to encode his name into The Art of Fugue, and it breaks off unfinished soon after he introduces that motif.
- Even more possibilities occur when you consider that E-flat is written Es, F-sharp is Fis, etc. Dmitri Shostakovich used DSCH (= D - Eflat - C - B) in many of his works.
