## What it is
A Symfony polyfill library providing native PHP implementations of the intl extension's grapheme_* string functions for environments where the Intl extension is unavailable. It supports functions like grapheme_strlen, grapheme_substr, grapheme_strpos, and grapheme_str_split on UTF-8 strings.

## Use cases
- use grapheme_* functions without the intl extension installed
- count string length in grapheme units on hosts lacking intl
- split strings into grapheme clusters in pure PHP
- portable unicode string handling across PHP deployments
- find substring positions in grapheme units without ext-intl

## When to choose
- your PHP runtime lacks the intl extension but you need grapheme cluster string operations
- you want portable code that works with or without ext-intl
- you already use Symfony components and need consistent unicode handling

## When to avoid
- the intl extension is already installed and you prefer the native C implementation
- you need full ICU unicode support beyond the grapheme_* function subset

## Facets
- artifact type: library
- maturity: stable
- function: internationalization, parser
