Beschreibung

public static function IntlChar::charFromName(string $name, int $type = IntlChar::UNICODE_CHAR_NAME): ?int

Finds a Unicode character by its name and returns its code point value.

The name is matched exactly and completely. If the name does not correspond to a code point, null is returned.

A Unicode 1.0 name is matched only if it differs from the modern name. Unicode names are all uppercase. Extended names are lowercase followed by a hyphen followed by an uppercase hexadecimal number, and within angle brackets.

name

Full name of the Unicode character.

type

Which set of names to use for the lookup. Can be any of these constants:

Rückgabewerte

The Unicode value of the code point with the given name (as an int), or null if there is no such code point.
