How's your code looks like?

I've attached a lite .Net project to give an example,

It seems the problem occurs only when a record is updated not on insert.

The first refresh in UI update the first record and insert another one (Name = "éléphant" for both).

The second refresh show the result of the update ("éléphant" -> ".l.phant" for updated, "éléphant" don't change for inserted).

update :

In the console output i saw that EF uses the type "Text" for this column instead of "VarChar".
I reproduce the same behaviour using FbCommand with a parameter of type "Text" too.
I don't know why but I if I specify "VarChar" in the mapping the update statement continue to use "Text" and do this bug :(

You should use UTF-8 charset for your connection.
