Special characters

Hi,

Is there a possibility that your posts starting with ? might include variations on the character/letter that aren’t accounted for in the default alphabet? The “Unicode” character number needs to exactly match, so even if two letters look similar they could be considered by Unicode to be different.

If you’re sure that they should be the same, try copying the first character/letter from the title of the (a) post that is correctly sorted and paste it into the title of one of the posts that is being treated wrongly and save that post to see if it makes it work. If the post you just edited is now correct then it would seem that you have similar letters that are actually different Unicode letters.
