Thanks! It helped. When I changed the connection url to
lc_ctype=ISO8859_1 it worked like a charm. However, the string I tried
to insert didn't contain anything outside the normal ASCII range (only
looked at it briefly) so perhaps a string larger than 256 characters are
read differently with charset NONE (JayBird default I suppose) compared
to charset ISO8859_1. Very well, not it works again.

Thanks for helping me regain my (very short) lost confidence for
Firebird 8-).
