Convert fancy Unicode numbers (such as โ , ๐, ยฒ or โ) into standard ASCII digits (0โ9). This Unicode number normalizer online detects and fixes circled numbers, mathematical digits, superscripts and subscripts that can break SEO, numeric parsing, and data consistency.
The Unicode Number Normalizer by kovertiz converts non-standard Unicode numeric characters into plain decimal digits. This ensures consistent numeric behavior across search engines, databases, programming languages, and operating systems.
Designed for production environments. All normalization runs entirely client-side using deterministic Unicode mappings. No input data is transmitted or retained.

Learn how to normalize Unicode numbers, convert fancy digits, and fix non-standard numeric characters for SEO, databases, and cross-platform text compatibility.
Unicode fancy numbers include circled digits (โ ), mathematical numbers (๐, ๐ ), superscripts (ยฒ), and subscripts (โ). Although they look like normal digits, they are different Unicode code points, which can break SEO indexing, form validation, and database queries.
Unicode number normalization scans your text for non-ASCII numeric characters and converts them into standard digits (0โ9). This ensures numeric values behave consistently across browsers, search engines, and programming languages.
Yes. This Unicode number normalizer supports circled numbers, mathematical digits, superscripts, and subscripts. You can normalize all styles or target a specific Unicode number category.
Search engines treat Unicode digits and ASCII digits as different characters. This can cause duplicate content, broken structured data, and inconsistent keyword matching. Normalizing numbers ensures SEO-safe text, clean URLs, and accurate metadata parsing.
Yes. You can exclude specific digits using the Keep Symbols option. This is useful when certain Unicode numeric symbols are required for design, branding, or mathematical notation while normalizing the rest.
Absolutely. All Unicode number conversion runs locally in your browser. No text, numbers, or data are uploaded or stored, making this tool ideal for secure data cleaning and privacy-sensitive workflows.
