Hi frens. I have tried to prepare an alternate spelling system/orthography for the Urdu language to help remove homographs and the problem of ambiguity in reading for learners. This can be done by making it compulsory to use existing diacritics to represent short vowels, gemination and dead consonants, and also introducing new diacritics to represent the long vowels. I think we can achieve a phonemic orthography for Urdu by following these rules:
>Compulsorily indicate the short vowels "i" and "u" in middle/final positions of a word using the diacritics zer ( ِ ) and pesh ( ُ ) respectively on the consonant after which they immediately occur. When there is no diacritic on a consonant in an initial/middle position of a word, it is assumed that the consonant is followed by the inherent short vowel "a", unless the consonant is followed by a long vowel or do chashmi ha (ھ). In those two cases, the consonant is treated as if dead. If there is no diacritic on a consonant in the final position of a word, it is treated as a dead consonant.
>Represent the short vowels "a", "i" and "u" at the beginning of a word using the letter alif without any diacritic, with zer, and with pesh respectively, i.e. ا and اِ and اُ respectively.
>Compulsorily indicate gemination wherever it occurs using the diacritic shad ( ّ ) over the geminated consonant.
>Represent a dead consonant in an initial/middle position of a word by using the diacritic jazam ( ْ ) over the consonant. Note that this is not done when the dead consonant is at the final position of the word. A consonant without any diacritic at the final position of a word is usually automatically treated as dead. Also, sometimes seemingly dead consonants at the middle position of a word are not marked with a jazam (obligatory schwa deletion).
