Sorry I don't understand what you mean with this.

Unfortunately I don't have Delphi > 2007. From what O read I understand 
that the dynamically code string type can hold 1, 2, and 4 byte (maybe 
even more) Codes for it's elements (denoted in one control-value) and 
each of those (theoretically) in different coding schemes (denoted in 
another control-value), allowing e.g. for UTF-8, UTF-16, UCS4, German 
ANSI, raw Byte, string....

Each assignment would auto recode the string "if necessary". I suppose 
that s1 := s2 would not do any recoding, but s1 := s2 + s3; would 
automatically synchronize the coding.

I suppose there are ways do define the coding (and force recoding), 
maybe similar to "setlength(s, 10)".
