Obviously UTF8Pos() and UTF8Copy() are a lot slower than Pos() and 
Copy(), and in many cases (i.e when that arguments of copy are obtained 
by Pos(), Length, ... ) Copy does what is requested. If single 
characters are the point of interest, this will not work. (Some easy to 
find and to read entry-level documentation on this would be nice, though 
:-) .)
