You can safely continue parsing. You can even jump to somewhere into an UTF-8 string and find the next character start. The problem is that you can no longer reverse without data loss. OTOH returning an empty string is even more data loss ... . > PS: Maybe this discussion should be moved to the FPC list ? The conversion must be somewhere, either in the db controls (lazarus), or in the db connector (fcl). Because the FCL prefers system encoding it might be a more lazarus problem.
