I have to say sorry. Over the day I lost track of tickets pointing out problems with emoticons so I failed to close the tickets after the first one as duplicates with the result that the information is spread all over the tickets.
That's why I'm going to try to collect all issues in this new ticket.
The following issues with emoticons have been reported:
"Crying" emoticon: :'(, according to #10025 and #10032 it's case sensitivity
"The Disappointed and the Eye-Rolling emoticons are the same" (pi++ in #10010)
(wontfix per evands in #10010 as the difference is the animation in eye-rolling and this is fine)
"I don't know if this is intentional, but :P is not recognized as an alias of :-P" (pi++ in #10010) (evands: worksforme in the default set)
":-[ needs to be added to embarrassed" (Pash91 in #10032) (evands: wontfix: I've never seen this one used for 'embarrassed', and Wikipedia's List of Common Emoticons doesn't know about it either.)
":-* is common for kiss, it is listed as whisper in this release" (Pash91 in #10032)
":d doesn't work as an alias for the :-D emoticon in the MSN set. This might be the case for all emoticon sets? :s, :o and :p do work." (lorre in #10032) (evands: wontfix: :d doesn't look like :D or :-D. It doesn't make sense for them to be equivalent.)
