+> ### _Detect whether the terminal supports advanced Unicode._
+
+Checks if terminal supports advanced Unicode (CJK, emoji, etc.) by measuring the cursor position of a single, wide char (𠀀). On Windows, returns `False` for legacy consoles (CMD). On all other modern terminals, returns `True` if the wide char renders as 2 columns.
+
+## ⚡ Installation
+
+```bash
+pip install is-unicode-supported
+```
+
+## 💻 Command line usage
+
+```bash
+$ is-unicode-supported  # or isunicodesupported
+
+True
+```
+
+CLI options:
+
+| Option            | Description
+| ----------------- | -----------------
+| `-h`, `--help`    | Show help screen
+| `-v`, `--version` | Show version
+| `--docs`          | Open docs URL
+
+## 🔌 API usage
+
+```py
+import is_unicode_supported
+
+if is_unicode_supported():
+    print('Advanced Unicode supported!')
+else:
+    print('Advanced Unicode not supported!')
+```
+
+_Note: Most type checkers will falsely warn_ `is_unicode_supported` _is not a callable module because they are incapable of analyzing runtime behavior (where the module is replaced w/ a function for cleaner, direct access). You can safely suppress such warnings using_ `# type: ignore`.
