Registration alone is not a production-quality guarantee. |\n| Browser execution | Automatic updates after valid input or file selection. |\n| Browser processing | Browser; see tool notes for network behavior. |\n| HTTP API | Not callable through HTTP. |\n| Browser-agent interface | run_current_tool |\n\n### Implementation notes\n\nNFC combines equivalent accents; NFD separates them. NFKC and NFKD also change compatibility characters such as full-width letters. Review the result before replacing identifiers.\n\n### Inputs and settings\n\nText input: Your text.\n\nExample or placeholder shown in the interface (not a validated fixture):\n\n```text\nType or paste your input…\n```\n\nChange the input or settings to update your result. Results update as you type. Up to 1,000,000 characters.\n\n| Setting | Meaning | Control type | Default | Constraints |\n| --- | --- | --- | --- | --- |\n| `form` | Normalization form | select | \"NFC\" | Allowed: NFC, NFD, NFKC, NFKD |\n\n### Browser-agent workflow\n\n1. Open the human page in a browser that supports WebMCP.\n2. Discover the interface exposed by that page; use its actual schema.\n3. Select files on the page first when the tool requires files.\n4. Call `run_current_tool` with valid input and settings.\n5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.\n\nCalls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.\n\n### Planning specification\n\nNFC combines equivalent accents; NFD separates them. NFKC and NFKD also change compatibility characters such as full-width letters. Review the result before replacing identifiers.\n\nThis describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.\n\n### Complete machine-readable capability record\n\n```json\n{\n  \"id\": \"normalize-unicode\",\n  \"category\": \"text-tools\",\n  \"built\": true,\n  \"requirements\": \"NFC combines equivalent accents; NFD separates them.
