Today a Lady was emailing me, An at the end of every email there was a “J”. Her name did not start with a J. So i was a bit confused…..
It turns out that “J” is displayed when a Smiley gets lost in different email systems.
I thought I had it figured out, and so I went looking to see & I was right. Have you ever typed a smiley 
, and whatever program you were in automatically made it into a smiley? Well, sometimes the code that makes that happen gets lost as it goes through the various email programs and ends up as just a "J"
Update for precision:
- Office use MS Word as HTML e-mail editor
- The "smiley" is replaced by a Winding font character.
- The uppercase "J" is a smiley in the Winding character set.
- The "J" will appear each time the text is kept but the font info is lost.

So there you have it. Its a smiley face, lost in translation!
