Tips & Best Practices
💡 Start with a preset and customize – it's faster than building from scratch.
🌍 Use \p{L} for Unicode property matching instead of [a-zA-Z] for better international support.
⚡ Don't forget to test edge cases like hyphenated surnames or apostrophes.
🔒 Always set reasonable length limits to prevent potential regex attacks.
📚 Familiarize yourself with the "Lookahead" syntax for complex password/name rules.
Common Questions
What is a name regex?
A name regex is a regular expression pattern designed to match names. It can enforce rules like starting with a capital letter, allowing spaces, or supporting Unicode characters for international names.
How do I support accents and international characters?
To support international names, use Unicode character ranges like À-ÿ or preferably Unicode properties like \p{L} in modern regex engines. This ensures names like "José" or "Артём" are correctly validated.
Why should I use weight-based validation for names?
While names are usually validated by pattern, some systems use "entropy" or "weight" to ensure names aren't just random characters. However, for names, precise pattern matching is usually preferred over complexity scores.
