Calgary engineer believes he's cracked the mysterious Voynich Manuscript

Not to be rude Ahmet, but you've lost me.
I called them Arabic numerals because that is the English name for the ten decimal digits written in the form 0123456789.
I called them modern European style because the symbol you discussed (2) is graphed in a modern European style.
Arabian, Persian, tamil, Hindu all use the same characters but graph them in a different way.
The symbol for 2 was just starting to replace the old symbol in the middle of the 15th century in Europe. Before then the digits were written differently. This has been amply discussed elsewhere.
So my question remains - would a Turkish writer, who is not using the Latin alphabet, have known the symbol for 2 in this fashion and used it this way? If 2, why not 4,6,7?
This image shows how the digits were written old style in French Manuscripts from c. 700 to c1500
