Q and X are special. The Q sound is written as "KW" so the word "QUEEN" would be spelled "KWEEN"
Same goes with X except it uses the "KS" sound. So the word "BOX" would be "BOKS"
Also, if the X makes a "Z" sound like in xylophone, it gets replaced with "Z".
I forgot the symbol for J. I'll PM you a pic with the entire alphabet, including punctuation.
