	/// of the same functions in Poco/String.h.
	///
	/// The various variants of icompare() provide case insensitive comparison
	/// for UTF-8 encoded strings.
	///
	/// toUpper(), toUpperInPlace(), toLower() and toLowerInPlace() provide
	/// Unicode-based character case transformation for UTF-8 encoded strings.
	///
	/// removeBOM() removes the UTF-8 Byte Order Mark sequence (0xEF, 0xBB, 0xBF)
	/// from the beginning of the given string, if it's there.
