[UA-discuss] Mixing between RTL and LTR scripts

[Zied BOUZIRI]

Hi
I think that mixing RTL and LTR scripts is not good idea, we will have
multiple confusions :
How we read domain name or email address ? from the RTL or LTR ?
It is clear that for the arabic language, domain or email address are
written and read as  RTL,
In other hand, mixing arabic with punctuation and emojis will not produce
confusions, domain name or email adresses still read and written as RTL.
Best regards
