Hi İbrahim, I worked on the subject and found some workings and documents that confirms that all ottoman letters have Unicode correspondence. I am going to finetune trained models as Shree advises.
Here are the samples of the four letters and the Unicode values : ﭖ : %uFB56 ﭺ : %uFB7A ﮊ : %uFB8A ﮒ : %uFB92 ﯓ : %uFBD3 Selamlar On Tue, Dec 24, 2019 at 6:19 PM Ibr <ibr.ham...@gmail.com> wrote: > Hi Serkan, > > if Ottoman Letters have code to represent them then yes its doable > > On Friday, December 20, 2019 at 12:06:56 AM UTC+2, Serkan Taş wrote: > >> Hi Ibrahim, >> >> According to Shree's advices I am going to work on training for some >> time, of course before I am going to work on the alphabet and other symbols >> in arabic and farsi dataset which are common with ottoman.
