Unicode Diacritic Accent & Arabic Tashkeel Stripper
Remove all combining accents, umlauts, cedillas, tildes, Arabic/Urdu Harakat (Zabar, Zer, Pesh, Shaddah), Hebrew Niqqud, and Vietnamese tone marks while preserving clean base letters.
The Linguistic Engineering of Unicode Diacritics & NFD Decomposition
In writing systems across the world, diacritical marks (such as accents, umlauts, cedillas, and vowel points) modify the phonetic value or pitch tone of a base consonant or vowel.
In digital computing, characters with diacritics exist in two distinct formats:
é (U+00E9).e (U+0065) + ◌́ (U+0301).Our stripper uses NFD Canonical Decomposition to separate all combined accents from their root base characters, then applies high-performance regex filters to delete combining marks while leaving the base consonants and vowels intact.
Critical Applications for Diacritic Stripping
- •SEO URL Slug Generation: Clean foreign city names and titles into URL-safe ASCII slugs (e.g.
/posts/sao-paulo-zurich). - •Arabic Search & NLP: Normalize Quranic or classical Arabic text by stripping Tashkeel so search queries match unvowelized user input.
- •Database Full-Text Indexing: Ensure user search queries match customer names regardless of accent variations (e.g. “Muller” matches “Müller”).
- •Data Science & Machine Learning: Reduce vocabulary sparsity and improve tokenization efficiency in LLM training datasets.
