I'm using the Album Photo endpoint to upload a photo into an album on a page. I'm using the "caption" paramater to set a caption that includes an emoji. The caption is set but the emoji is replaced by the little question mark broken-character unicode symbol.

The same thing works when posting photos to the feed and used to work here as well. So seems like a bug. I did try to report a bug but the bug report page says to post here, so here I am.

Does anyone have any idea if this might be fixed in the future?
