Question on the length of VarChar?

[Thierry Nauze]

Hi,

At the moment I have an encoded MacRoman database with, for the example,
VarChar (8) which are enough for what I make.

Let us suppose that soon I like to be able to put in it 'Вячеслав' ou
'Éçäôñùvà'. 
It will be necessary for me to change the encodage (OK) and my VarChar
(8) will be insufficient.

My question: 
If, to record the same data, I define at the moment my varchar ( 256 )
instead of varchar (8)...

Is the size of the data base going to get grow as a consequence?
Will there be a loss of speed in the search ?


I work on Mac with RB 5.54 and Valentina 1.1

Thank you beforehand
