After joining Microsoft I quickly learned that the glyph in the Wingdings font for J is a smiley face. How did I learn this? Word automatically autocorrects :) into J if you let it. (Non-Windows users might not see a smiley in that sentence.) I seem to be the only person who hates that and turns that off immediately. So, whenever someone sends me a short mail ending in a smiley, the little new mail notification toast that pops up from Outlook looks like this:
Yeah, I'll get right on that. J
The new mail notification, as you might expect, shows everything in Tahoma, not the actual font that person used to write their email. And that's how I learned how to make a smiley with the Wingdings font.
