Buffer end before end of clumplet - clumplet too long
This error shows up when some buffer in code that uses Firebird API directly is too small to hold the data. If you use Firebird API directly from C, check your code. Otherwise it may be a bug in your connectivity library. It is also a common error message when you don't use multibyte character sets properly (for example UTF-8). Here's how to setup UTF8 for Java/JDBC:
info.put ("user",getUser ());
info.put ("password",getPassword ());
info.put ("charSet", "UTF-8");
info.put ("encoding", "UTF8");
The reason for this is that 'charSet' requires Java character set name and the 'encoding' requires Firebird character set name.
