Understanding Diacritic Removal
Diacritics are accent marks (e.g., acute ´, umlaut ¨) added to letters for pronunciation in languages like French (é), Spanish (ñ), or German (ö). This tool uses Unicode Normalization Form D (NFD) to decompose characters into base + mark, then strips the marks, yielding plain ASCII (e.g., é → e).
Example: Input " naïve façade " → Output "naive facade" (with trim: "naive facade").
- NFD Process: Splits combining sequences; regex /[\u0300-\u036f]/g for removal
- Scope: Covers Latin-1 Supplement to Extended-A; ignores non-decomposable
- Benefits: Reduces charset issues in databases or URLs
Validates with patterns like /[\u00C0-\u017F]/ for accented ranges in preprocessing.
Advanced Features & Capabilities
Batch Processing
Handles multi-line or paragraph text at once, ideal for cleaning bulk data like CSV imports.
Case Sensitivity
Maintains upper/lower case during normalization; no forced lowercasing for title preservation.
Error Feedback
Indicates unchanged characters or warnings for non-supported scripts to guide users.
Frequently Asked Questions
Does it support all languages?
It supports most diacritics via Unicode normalization (NFD) for Latin scripts and common global marks. Extremely rare or script-specific ones (e.g., Arabic) may not be fully covered—focus on European/ASCII transitions.
Is the accent removal safe for SEO?
Yes. Removing accents is a standard practice for generating SEO slugs and improves URL readability and compatibility across search engines like Google.
Does it change numbers or punctuation?
No. Only diacritic marks are targeted and removed; numbers, symbols, spaces, and other punctuation remain unchanged.
What happens to unsupported characters?
They are preserved as-is; the tool focuses on removable diacritics, falling back gracefully for emojis or non-Latin scripts.
Is it reversible?
No, as it discards accent information permanently. For round-trip, keep originals; use for one-way cleaning like slugs.
How does it handle capitalization?
Fully preserves: Uppercase accented (É) becomes E, lowercase (é) becomes e—matching original case.

Integration & Code Examples
Implement diacritic removal in JavaScript using normalization for custom functions:
JavaScript Example:
// Function to remove diacritics
function removeDiacritics(text) {
return text
.normalize('NFD') // Decompose Unicode
.replace(/[̀-ͯ]/g, '') // Remove combining diacritics
.normalize('NFC'); // Recompose if needed
}
// Example usage
console.log(removeDiacritics('José's Café résumé')); // "Jose's Cafe resume"
