PHP IntlChar()

PHP 7 supports internationalization (i18n) and localization (l10n) through the intl extension. This extension is just a basic wrapper for the ICU library and provides similar methods and features to the ICU library.

PHP 7 exposes the Unicode character features in ICU through the new IntlChar class. This class itself defines many static methods for operating unicode characters from multiple character sets.

The above program execution output result is:

10ffff COMMERCIAL AT bool(true)
