Just for clarification, inside the tagcloud each arabic string has the letters attached from left to right (so first letter to the left, second right after it)?

this arabic letter is from right to left attached to each other

expected : أحمد
output : دح م أ

which is very wrong and not readable at all, in arabic first letter is on the right then the second to its right and so on

That was actually an issue in our UI framework EUI, and fixed as of elastic/eui#1960. This issue will be resolved in some further Kibana versions that uses the fixed EUI version.
