Sorting a list containing text and emojis

We have a mail client that displays the folders of the mail account in a list. I am not sure, how to sort the folders when the user has "strange" folder names like emojis. This should not be underrated: many people user folders named like ☑️ or ✮ to give them a meaning. iOS is sorting a snowman ☃ before an A, but in php will put the snowman at the end of the list. The list is not sortable manually.
