Looks like the vertical bar character | is being pasted as '. Is there a bug in the character map? Hopefully this can be fixed as my language thread (http://channel9.msdn.com/Forums/Coffeehouse/Prototyping-New-Language-With-Haskell) doesn't make sense with this mix-up.
To reproduce, create a new forum posting, enter a |, then copy and paste it. Always comes out as ' for me.
