Huh, TIL that Outlook replaces all smiley faces with "J" in plain text emails
Apparently they decided to auto change ":)" to the windings smiley face in anything you send, and when that gets converted to plain text you end up with "J"
Because Microsoft evidently haven't heard of the emoji block in unicode
That bug's been in there since 2010
@troubleMoney Solution: have a bit of code for plain text emails in outlook that comes in afterwards and replaces all the "J"s with ":)" again. :D
