Package description

What is astral-regex?

The astral-regex npm package is designed to provide a regular expression for matching astral symbols in text. Astral symbols are Unicode symbols that consist of a pair of surrogate halves and are used to represent characters outside the Basic Multilingual Plane (BMP). This package is particularly useful for applications that need to process, validate, or manipulate text containing such symbols, ensuring compatibility with the full range of Unicode characters.

What are astral-regex's main functionalities?

Matching astral symbols

This feature allows you to match and extract astral symbols from a string of text. The code sample demonstrates how to use the package to find astral symbols within a given string. In this example, the astral symbol '𠮷' is successfully matched and extracted from the text.
