[Firebird-net-provider] bug report: UNICODE_FSS + CHAR causes exception

[Anders Eggers-K. <di...@ae...>]

I have a CHAR(32) field in my database using UNICODE_FSS as charset
trying to insert a string of 32 chars using=20
INSERT MyTable (ColumnName) VALUES (?)
causes an exception in GdsInetWriter.WriteOpaque
in the line Write(fill, 0, len - buffer.Length);

the value of len is 32 (presumably the size of the CHAR(32) field)
buffer.Length is 96 (why it is not 64 I don't know... thought unicode=20
was 2 bytes per char)

The resulting exception is:

System.ArgumentOutOfRangeException: Non-negative number required.
Parameter name: count

count)
