The Windows Phone Blog has posted a chart of emoticons (aka emoji) that you can find on Windows Phone.
"Turns out Windows Phone 7.5 has a ton of built-in emoji--many of which were totally new to me! Here are the key combinations for conjuring just a few of them. Yes, there are more," blogged Michael Stroh.
Watch this post again on next Tuesday for part two.
Here is the pat 2 of the Windows Phone 7.5 emoticons. "Because there isn't a single global standard, these character combos might call up different images (or none at all) if you send them to people not using Windows Phone 7.5 or Windows Live Messenger," said Michael Stroh.
