Why are my final characters truncated when converting from DT_WSTR to DT_STR?
Casting from a DT_WSTR to a DT_STR with the same charcountvalue may cause truncation of the final characters in the converted string. If sufficient storage is available in the column of the destination table, set the value of the charcountparameter to reflect the number of bytes that the multibyte code page requires.

What is Nvarchar vs varchar?
