transliteration chart for arabic: (for letters with a green background: i'm very sure that the transliteration is correct. I'm not sure about the ones with orange background. their transliteration was chosen in such a way that the most frequent letters correspond to the most frequently used letters in Latin alphabets and preferential assignment of vowel-like letters to vowels and consonant-like letters to consonants. letters beginning with a small "s" are typed with "shift"+letter)
