Unicode → ASCII Transliterator

· Last updated：2026-07-30

Convert any Unicode text to plain ASCII: strip accents (é→e, ñ→n), romanize Cyrillic/Greek, and transliterate Chinese to pinyin (北京→Bei Jing). Drops emojis and symbols that have no ASCII equivalent.

Details

What this tool helps you do

A lossy-but-readable conversion from full Unicode to 7-bit ASCII. Latin combining marks are stripped (Façade→Facade, Ångström→Angstrom), non-Latin scripts are romanized (Привет→Privet, Αθήνα→Athina), and Chinese characters are converted to pinyin via pinyin-pro with correct polyphone handling (重庆→chong qing). Japanese kanji come out at pinyin grade since true romaji requires a morphological dictionary. Useful for building ASCII-only filenames, search indexes, slug precursors, legacy-system data entry, and cleaning copy-pasted text that carries invisible Unicode. Shows a before/after non-ASCII count so you can confirm the result is pure ASCII.

Overview

Unicode → ASCII Transliterator converts text into readable 7-bit ASCII by removing Latin accents, romanizing Cyrillic and Greek, and converting Chinese characters to pinyin. Characters without an ASCII equivalent can be dropped or kept as-is.

When to use

  • Create ASCII-only filenames and slug precursors from text containing accents or non-Latin scripts.
  • Prepare multilingual text for legacy systems or data-entry fields that accept only ASCII.
  • Clean copied text and check the before-and-after count of non-ASCII characters.

How it works

  1. 1Paste the text to transliterate into the text field.
  2. 2Choose whether non-translatable emojis and symbols should be dropped or kept.
  3. 3The tool removes Latin diacritics and romanizes supported non-Latin scripts, including Chinese to pinyin.
  4. 4Review the converted text and the non-ASCII count to verify the result.

Use cases

  • Generate readable ASCII-only filenames from multilingual text.
  • Create a plain-text precursor for search indexes or URL slugs.
  • Clean multilingual copy before entering it into systems with ASCII-only requirements.

Examples

1. Convert mixed-script text for a legacy field

Data-entry specialist

Background

A data-entry specialist receives names and location text containing accented Latin, Chinese, and Cyrillic characters, but the destination system accepts ASCII text.

Problem

The source text needs to remain readable while unsupported characters are removed or romanized.

How to use

Paste "Café 北京 Привет" into the text field and leave Unknown handling set to Drop non-translatable.

{"text":"Café 北京 Привет","keepUnknown":"drop"}

Outcome

The accented Latin text is deaccented, 北京 becomes pinyin, and Привет is romanized into readable ASCII.

2. Resolve a Chinese polyphone in a search index

Search engineer

Background

A search index needs an ASCII-friendly version of Chinese place names, including a character whose pronunciation changes by context.

Problem

A generic character mapping could produce the wrong pronunciation for 重庆.

How to use

Paste "重庆和北京" and use the default Drop non-translatable setting.

FAQ

What does this tool convert?

It converts Unicode text to readable ASCII, including accented Latin, Cyrillic, Greek, and Chinese text.

How are accented letters handled?

Accents and other Latin diacritics are removed, so é becomes e and Å becomes A.

How is Chinese transliterated?

Chinese characters are converted to pinyin, with polyphonic characters handled according to their context where supported.

What happens to emojis and symbols?

By default, non-translatable emojis and symbols are dropped. You can choose to keep them as-is.

Will the output always be pure ASCII?

Yes when non-translatable characters are dropped. Keeping unknown characters can leave non-ASCII characters in the output.
