Here is the caller graph for this function:

QString LexAn::readStringBetween	(	const QChar &	opening,
		const QChar &	closing,
		bool	allowMatching = `true`
	)

reads string between characters pair, if allowMatching is false, first closing character stops reading, otherwise balances matching is used never call matching on opening character, but ever call matching to closing character!
