Unicode Normalizer
Convert text to different Unicode normalization forms (NFC, NFD, NFKC, NFKD). An essential tool for developers dealing with text processing, data validation, and internationalization to ensure consistency.
The Unicode Normalizer is a technical utility for developers, linguists, and data scientists who work with international text. In Unicode, a single visual character (like 'é') can sometimes be represented by multiple different byte sequences. For example, it can be a single pre-composed character or a base character ('e') followed by a combining accent mark ('´'). This ambiguity can cause issues in searching, sorting, and data validation. Normalization is the process of converting all text to a single, consistent representation. This tool allows you to convert text to any of the four standard Unicode normalization forms, ensuring that your text data is consistent and reliable.
How It Works
- Input Text: Paste the text you wish to normalize into the left-hand input area.
- Observe Initial State: Note the initial character and byte count below the input box.
- Select Form: Choose the desired Unicode normalization form (NFC, NFD, NFKC, or NFKD) from the dropdown menu.
- Normalize: Click the "Normalize" button. The result will appear on the right.
- Observe Change: Even if the text looks the same, compare the byte counts. For example, converting 'é' from NFC to NFD changes its byte length from 2 to 3, proving the underlying data has changed.
