Its fully clear now. Thanks a lot, olaf. It helps a lot when the basics become clear.

It is really so kind of you to take the extra mile, for my sake, and provide additional explanatory statements like "...and as such, should not be fed e.g. into any Text-expecting or Text-Conversion-routine like ... .. .", "without interpreting, or converting it in any way" and "in short, the VBString-Type is able to store 'arbitrary byte-sequences' (which are not WChars) but ... .. ." . These helped me so much, to get that perfect clarity in my mind. Thanks a lot, once again.

Kind Regards.
