Game character names used to do that. The acronyms I always said how they were spelt though. Except for Jpg (or Jpeg) or Mpg (Mpeg). And Gif. I do those cos they have vowels.
Like, Edea from FF8, I pronounced Ed-ear. I found out is was meant to be E-da.
Also, Yoshi. I prefer Yoh-She. Some go Yow-she.
Strangely though, I got Sephiroth right though. Seh-fear-roth.
..er, I got one. Hegemonic. Hegg-e-monic or Hedge-e-monic? Also diegetic. Die-e-gee-tic or Die-e-jet-ic?
