Not only this, but the normal user would like to do

   MyChar := MyString[Length(MyString];

to get the last character of a string.

This would only work if length is counted in Unicode characters 
disallowing the use of length in stream I/O (such as file read) functions.

Thus IMHO the Length function name should be dumped and two new 
functions (such as CharacterCount and ByteCount) should be introduced.

We obviously  would need a UnicodeChar Type that holds the 32 Bit encoding.

But the said "quirks" can't be handled by this. I up till now don't 
understand if - technically - these "quirks" are seen as a single 
Unicode character or as a sequence of Unicode Characters. Nor do I 
understand how they can be used in a decent way and if they are 
necessary or just legacy.
