It seems that etsy is now placing a '?' at the end of titles that are long. I looked at the following listing:
'Floral Triangle Banner, Women's Bunting Banner, Birthday Party Supply, Long Feminine Banner, Girls Photo Prop, Party Decor Streamer'
This is what the URL looks like, that one would copy from address bar:
[NOTE: quotes added to prevent link becoming active]
Notice the question mark where the title is truncated.
When the URL is now copied and pasted into a thread comment, without quotes, the listing will render with picture but the ? will not be considered part of title so it will post below rendered picture as text.
I saw a comment from admin, regarding this issue (saying it was probably a user error with cut and paste) in another bug post, however, I believe the comment not correct. The question mark has just started appearing in the past four or five days and it would seem that is due to some change made by etsy regarding truncation of long titles.
NOTE: it also appears that the character count for what is considered 'long title' may have changed. I have reviewed many listings that were not considered long in past and now they are truncated with the question mark.
To confirm that the question mark appears, look at items in your shop and you will see the URL with ? at end. If you just copy/paste that URL, you will see issue that Jenni and others are reporting.
