Unfortunately, very aesthetic native lettering invite problems in the
context of modern technology.

Reminds me of the Turkish alphabet revolution anticipating future
benefits https://en.wikipedia.org/wiki/Ottoman_Turkish_alphabet.

IMOH aesthetic native scripts or phonetic mixed forms of native scripts
is suitable for art, not for modern technology and international
networking, regardless of a rating, i.e. whether the decisions were
right or wrong, they were made long ago.

In my opinion, it makes more sense to introduce and get used to a Latin
alphabet with additional characters than to stick with fonts based on
old handwriting.
