Anmerkungen
By contrast to strtolower(), 'alphabetic' is determined by the Unicode character properties. Thus the behaviour of this function is not affected by locale settings and it can convert any characters that have 'alphabetic' property, such as a-umlaut (ä).
For more information about the Unicode properties, please see » http://www.unicode.org/reports/tr21/.
