Types of Weird Codes on iOS
iOS devices offer many features and strong performance. However, some users see odd codes and characters on their screens.
Though these codes seem strange, they have a reason behind them. This article will explore the different weird codes on iOS, their functions, and how to handle them.
Unicode characters

Understanding Unicode characters can make it easier to use different systems, communicate globally, and work across cultures and languages.
