IntlChar::isIDPart — Check if code point is permissible in an identifier

### Description

public static IntlChar::isIDPart ( mixed `$codepoint` ) : bool

Determines if the specified character is permissible in an identifier.

`TRUE` for characters with general categories "L" (letters), "Nl" (letter numbers), "Nd" (decimal digits), "Mc" and "Mn" (combining marks), "Pc" (connecting punctuation), and u_isIDIgnorable(c).

> Note:

> This is almost the same as Unicode's ID_Continue (`IntlChar::PROPERTY_ID_CONTINUE`) except that Unicode recommends to ignore Cf which is less than IntlChar::isIDIgnorable().

### Valeurs de retour
