HELP with SQL and strings

[wizardnet]

Hi.

I have string what codec in UTF-8.
I using in =System.Text.Encoding.UTF8.GetString(bytes)
and save it to file.

now I loaded this file into normal string, but I see this string in "add watch", and it's show me this char: " (chr(34)) in text-window.

so when I append this to SQL string, I see in "add-watch" this char " before my string.

and DB is rejected this sql string.

how to fix it?
