UnicodeChecker
UnicodeChecker is a macOS utility for exploring Unicode characters, inspecting code points, and converting text between encodings and formats.
What is UnicodeChecker?
UnicodeChecker is a native macOS utility that helps users inspect Unicode characters and convert text between common Unicode-related formats. It is designed for developers, writers, typographers, and anyone who needs to understand how text is encoded, normalized, or represented behind the scenes. The app lets you browse characters by code point, plane, and block, search by Unicode name, and review related character data such as decomposition details. It also converts text to and from formats used in HTML, CSS, URLs, IDNA, and programming workflows. Built for Mac users, UnicodeChecker includes tools for comparing strings character by character and offers Services menu integration so parts of its functionality can be used from other apps.

Safety overview
Status: Safe
UnicodeChecker is a focused text utility for macOS and its behavior is consistent with its purpose. It works with text you provide and may integrate with standard macOS features such as the Services menu so you can send selected text from other apps for inspection or conversion. That kind of text access is normal for a Unicode analysis tool. As with any utility that processes copied or selected text, avoid sending sensitive information unless you intend to analyze it.
Recommendation: Keep UnicodeChecker if you work with character encoding, text conversion, web content, or multilingual text on your Mac. If you no longer use its Unicode inspection and conversion tools, you can remove it without affecting macOS itself.
