    IntlChar::charFromName — Find Unicode character by name and return its code point value

    Опис

    public static 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 an uppercase hexadecimal number, and within angle brackets.
