After receiving an official Windows Mobile 6.5 Update, the HTC Snap gets an official patch from HTC concerning the Inner Circle and its ability to display special characters.
According to the description, “this update lets you be more expressive with your Inner Circle friends by adding even more support for non-traditional characters. Use the words and characters you need to express exactly what you feel, whenever you want to; your HTC Snap will display it perfectly”.
This update is applicable to HTC Snap with Inner Circle versions Version 1.0 Build 1919.3324 and below so if your device has a newer version, you don’t need to apply it. And since it’s a patch update, you need to reapply it every time you Hard Reset.
