Ok, I can try prepare patch, but only "generic" i.e. which uses only Pascal.
Processor specific implementations (which use assembler, like it is done 
for AnsiString versions) I am afraid  is too dificult for me ATM ;-)
And also decision where to put (in which units) these functions I will 
leave to somebody more familiar with unit dependencies.

Yes, I will do it. I expect, that length is in this case "character 
length", so "byte length" is "character length"*sizeof(widechar)
