## Overview

The Unicode Escape Converter is a utility designed to convert text to and from Unicode escape sequences, such as \uXXXX or \u{XXXXXX}, and apply Unicode normalization forms including NFC, NFD, NFKC, and NFKD. It helps developers and localization specialists handle non-ASCII characters, resolve encoding issues, and standardize text representations across different programming environments.

## Inputs

- **Input Text** (textarea): Enter text or Unicode escape sequences...
- **Operation** (select)
- **Escape Style** (select)
- **Normalization Form** (select)
- **Escape Non-ASCII Only (skip ASCII)** (checkbox)

## When to use

- When you need to embed non-ASCII characters or emojis safely in source code files that require ASCII-only encoding.
- When decoding raw Unicode escape sequences from JSON payloads, logs, or API responses back into readable text.
- When standardizing text inputs using Unicode normalization forms (NFC/NFD/NFKC/NFKD) to ensure consistent string comparison and storage.

## How it works

- Input your raw text or Unicode escape sequences into the text area.
- Select the desired operation: convert text to escape sequences, decode escape sequences back to text, or apply Unicode normalization.
- Configure specific options such as the escape style (e.g., \uXXXX or ES6 \u{XXXXXX}), normalization form, or whether to escape non-ASCII characters only.
- The tool processes the input instantly and outputs the converted or normalized text.

## Use cases

- Encoding localized strings into ASCII-safe escape sequences for Java properties files or legacy JavaScript environments.
- Normalizing user-submitted text inputs to NFC form to prevent duplicate database entries caused by different character representations.
- Decoding obfuscated or escaped Unicode strings found in web application source code, API payloads, or server logs.

## Frequently asked questions

### What is the difference between the \uXXXX and \u{XXXXXX} escape styles?

The \uXXXX style is limited to the Basic Multilingual Plane (BMP), whereas \u{XXXXXX} is the ES6 code point format that supports supplementary characters like emojis without surrogate pairs.

### How does the 'Escape Non-ASCII Only' option work?

When enabled, standard ASCII characters (like English letters and numbers) remain untouched, and only special characters, accented letters, and emojis are converted to escape sequences.

### What are Unicode normalization forms like NFC and NFD?

NFC (Canonical Composition) combines characters (like 'e' and '´' into 'é'), while NFD (Canonical Decomposition) splits them. NFKC and NFKD apply compatibility formatting to standardize symbols.

### Can I convert Hex code points like U+1F600 back to text?

Yes, you can select the 'Hex code point (U+XXXX)' escape style and run the unescape operation to convert them back to standard characters.

### Does this tool support surrogate pairs for older environments?

Yes, you can choose the '\uXXXX Surrogate Pairs' escape style to represent characters outside the BMP using two 16-bit escape sequences.
