To follow up on the last comment by the vetter in the vetter:https://st.unicode.org/cldr-apps/v#/mr/Alphabetic_Information/7ed88347aa1b55ed
"Actually two letters are missing from “Main Letters” so we mentioned all main letters of our language. That time we assume that we can mention the kana, ukar, matra etc. in “Others: auxiliary” section. But while doing so system shows us error message that kana, ukar, matra etc. already available in “Main Letters”.
So, if there is any provision wherein we can submit a new translation with main letters and matras, ukar and kana then main letters will have complete translation"
