Thanks for the anwer. You are right.
This question is not new. I asked unicode organisation to have such a solution if there is a risk to wait 10 years to write chinese, japanese and persian, and RTL languages in one line of a sentence. If we cannot type ancient languages properly after years, how can we achieve speech recognition? Kids have mobile phone now.
The idea of this message is, to think objectivly, to help a blind person(speaking any human language) to live a better life with writing, reading and translating in different human languages.
Question: is there any code, regarding textlayout and linebreakmeasurer or others, to write LTR and RTL together?
Thanks and sorry for my language.
