Firebird returns the storage size in bytes and not the character length as 
field size. MSEgui DB components convert from utf-8 or the system encoding to 
widestring while fetching the field data. The field character length is get 
from Firebird metadata and applied to tmsestringfield as field size for 16 
bit characters.
