A consultant for a project using the Arabic script asked for help with a problem. When he inserted a note in English, and put in a word or so in the Arabic script, the note displays the beginning of the English sentence to the right and the end of the sentence to the left, like this:
.would be better مِسِرَ Perhaps
instead of:
Perhaps مِسِرَ would be better.
It turns out this can be avoided by changing the language in the edit note box to English, before starting the note. Doing so maintains the left to right text direction, even when right to left words are inserted in the English sentence.
