Use Unicode Normalizer

Normalize text with NFC, NFD, NFKC or NFKD and inspect equivalent spellings. Start with the sample, select the options and run the tool. Copy or download the result after reviewing it.

Behavior and limits

Canonical normalization composes or decomposes equivalent sequences. Compatibility forms also change characters such as fullwidth letters and circled digits. Select the form required by the consuming system before replacing text.

Example input

café ① Ａ

Expected behavior for the example

NFC produces café ① Ａ. NFKC also changes ① to 1 and Ａ to A.

Check important output in the application that will consume it. Use the tool directory to find related formats and tasks.
