Frequently Asked Questions

What languages does this tool support?

The tool supports any language that uses diacritical marks on Latin characters. This includes Vietnamese, French, Spanish, Portuguese, German, Polish, Turkish, Czech, Slovak, Romanian, Hungarian, Icelandic, Danish, Norwegian, Swedish, and many more.

Does it handle special characters like đ and ß?

Yes. The tool includes specific mappings for characters that cannot be handled by standard Unicode normalization alone. For example, đ becomes d, ß becomes ss, æ becomes ae, and ø becomes o.

Is my text sent to a server?

No. All text processing happens entirely in your browser using JavaScript. Your text never leaves your device, making it safe for sensitive content.

Will this tool change non-Latin characters?

No. The tool only processes Latin characters with diacritical marks. Characters from other scripts (Chinese, Japanese, Korean, Arabic, Cyrillic, etc.) are left unchanged.

Can I use this for creating URL slugs?

Yes. Removing diacritics is a common first step when generating URL-friendly slugs from international text. After removing diacritics, you can further process the text by lowercasing and replacing spaces with hyphens.

Why does ß become "ss" instead of just "s"?

The German letter ß (Eszett or sharp S) historically represents a double S sound. The standard transliteration is ss, which is also used in Swiss German and in uppercase German text (STRASSE for Straße).
