I notice people sometimes argue about whether the name of the titular mech of Gundam 00 is spelled "00-Riser" or 00-Raiser". This argument sprouts from a difference of pronunciation between English and Japanese of the sound "ai".
To translate it from its Japanese spelling of ００－ライザー, the literal spelling is "00-Raizaa", or 00-Raiser. In English, that would imply a spoken pronunciation similar to the phrase "00-Razor". However, anyone who's seen 00 in Japanese can attest that it's pronounced "00-Riser". In Japanese, the root "raise" would sound like "rise". In English, it sounds like "raze."
As an English speaker, the correct way to spell the name is 00-Riser. That is how the spoken pronunciation would be spelled in English. 00-Raiser is the Japanese spelling, and really only makes sense when written in kana.
