computer today bought in the past 5 years can display it, and because
it's different than ascii so it avoids ambiguity and complications.
e.g. when the quoted text also contains the char that you use for

thanks for your info. I'll think about removing them...

the other thing is that those markers are very useful when you think
about info processing and automation. e.g. in the future i can
