UTF8Encode converts a widestring to an UTF8 string. AsString returns an
ansistring. So the above first converts from system codepage to
widestring (UTF16) and then to UTF8.

I'm no sdf expert, so I will assume it does no conversion like most
If the csv file is in UTF8 and sdf does no conversion, then you can
simply load the csv file and don't need any conversion at all.
If the csv file is in the french windows code page 1252 then you can
use the function ConvertEncoding of the LazUtils unit lconvencoding to
convert its content to UTF8 before loading it into sdf.
