Hello Mirek,

I don't master all these caracter support problems but one thing that comes to my mind when I read you're proposition is:

• With 300 000 graphemes in a table ==> you get 1.2 MB of used RAM : no problem
• With 4 000 000 000 graphemes in a table ==> you get 12 GB of used RAM : this will be a problem before you run out of virtual characters

But I may misunderstand what you propose
