+ * @li QVariant::UInt - if the string begins with "0x", base 16 is used; if the string begins with "0",
+ * base 8 is used; otherwise base 10 is used;
+ * @li QVariant::Int - base 10 is used;
+ * @li QVariant::Double - the decimal point is expecte to be '.' regardless which locale is used;
+ * @li QVariant::Bool - tries to use isTrue() and isFalse() methods; otherwise performs a conversion to QVariant::uint;
+ * @li QVariant::Char - if the string begins with "\0x", expects it to be a UTF-16 code in hex; if the
