Hello, dinkumoil and All,
Your report of all your investigations was really interesting. So, as you say, we must live with that fact !
In return, you could find some interest, too, in reading these two technical reports, of the Unicode consortium, below, which can be used as a reference text :
http://www.unicode.org/reports/tr10/
http://www.unicode.org/reports/tr18/
I just have a glance to these documents, reading some parts and, like me, you’ll understand the complexity and richness of all the technical solutions envisaged to satisfy everyone, regardless of their mother tongue ;-))
By the way, I do like this sentence, given in the preamble of the link What is Unicode? :
Unicode provides a unique number for every character,
no matter what the platform,
no matter what the program,
no matter what the language.
Best Regards,
