Char is just a single byte.
So there are only 256 possible values of a Char.
Depending on your system codepage, Char's with a byte value > 127 have differnet meaning.
The text you have on the top of your message cannot be represented with 1-byte chars.
If you paste 1 "block" as you call it into the source editor, it will consist of multiple bytes.
Therefore if you need a variable to hold such a "block", the variable needs to be of the type String or UnicodeString.
