Some words return with "2" suffix

I just came across this:

original word: kağıttan
nuve result: kâğıt2/ISIM IC_HAL_AYRILMA_DAn

What is that "2" stands for?

Also is it possible prevent that diacritical letters (â)?

kağıt and kâğıt are two possible forms for the root. So nüve can recognize both kağıttan and kâğıttan. To be able to recognize a word's both diacritical form and regular form. Two roots are defined. 2 stands for this. For a while I'm considering another solution to get rid of both 2 the â in the root. I'm leaving this issue open to take an action about this as soon as I have some time.

Meanwhile, you can use regex.replace to get rid of those. Or you can edit those lines in the root.txt as follows and compile the project.

kağıt kağıd kâğıt2 ISIM isim, şapkasız YUMUSAMA_td, SAPKA_DUSUR_A

Just replace kâğıt2 with kağıt and remove the SAPKA_DUSUR_A rule.
