Why does my text look the same but count as different?
Computers represent characters like "ñ" in two ways: as a single code point or a combination of "n" + tilde. kovertiz standardizes these into a single format to prevent database indexing errors.
Normalize Unicode text using standard normalization forms such as NFC, NFD, NFKC, and NFKD. This tool helps ensure consistent character encoding and text processing across different systems and applications.
The kovertiz Unicode normalizer is a specialized utility for ensuring string consistency across different operating systems and databases. By applying the Unicode Transformation Algorithm , you can resolve hidden encoding discrepancies that cause search failures, database key collisions, and rendering bugs.
The professional tool for backend developers. At kovertiz , privacy is our core: all Unicode transformations are performed 100% locally within your browser.
Visualizing the canonical transformation process.
e + ◌́ (Two code points)
é (Single code point)
2 → 2 | ℌ → H
Quick guide to choosing the right normalization form for database consistency and string comparison.
| Form | Type | Behavior | Best Use Case |
|---|---|---|---|
| NFC | Canonical Composition | Combines characters (e + ´ = é) | Web display, Linux/Windows storage |
| NFD | Canonical Decomposition | Splits characters (é = e + ´) | macOS File Systems (HFS+ / APFS) |
| NFKC | Compatibility Composition | Composes & unifies symbols (2 → 2) | Search engines, Identifier matching |
| NFKD | Compatibility Decomposition | Decomposes & unifies symbols | Deep text analysis, Legacy data cleaning |

Yes. Our Unicode normalizer handles the entire spectrum, including Emojis, mathematical symbols, and non-Latin scripts, ensuring cross-platform compatibility for your text data.
Absolutely. kovertiz provides this and all other developer utilities 100% free. No registration is required, making it the fastest way to sanitize strings for your production code.
NFC (Canonical Composition) combines characters into one, while NFD (Canonical Decomposition) breaks them apart. kovertiz allows you to switch between them to match your backend requirements.
Yes. Consistent Unicode normalization prevents duplicate content issues in search engines. Using kovertiz ensures your URLs and metadata are SEO-friendly and properly encoded for all crawlers.
Privacy is our priority. Every string sanitization at kovertiz runs locally in your browser. Your sensitive strings or code snippets are never sent to a server, keeping your data private.
