What are invisible characters?

Invisible characters are special characters that don't have a visible representation in text but can affect how text is displayed, processed, or interpreted by software. Common examples include spaces, tabs, line breaks, and more complex Unicode characters like zero-width spaces. These characters are essential for text formatting and structure but can cause unexpected problems when they appear where they shouldn't, making them difficult to identify and debug without an invisible character detector or viewer.
