Feedback from Arabic translators the countries aren't in the correct order within each letter (i.e. alphabetical order by the second letter). Attaching a list showing the correct order provided by one of our Arabic translators.

I let them know that maybe we will go ahead as is and come to the second part later as it might take too much extra work.

from translation team

I’ve just noticed that in the French country pages, the alphabetical order in the lists of countries is a bit messed up. The letter é/É, which is the same letter as e/E (but pronounced differently), seems to be considered as a different letter by Wordpress. For instance, in the list of countries under E, all countries beginning with É are at the end of the list. Same, for instance, in the list of S countries, Sénégal is at the very end when it should be in second position. In the R list, all Républiques are at the end when they should be at the beginning.

I enclose 2 screenshots in case it helps you understand what I mean (I’m not sure I’m making much sense).
