 Description   

The code in storage/connect/. use the results of val_str() in
functions that assume 0-terminated string (e.g. strcat, strncat, etc).
This will have unpredictable results if the source Item character set
has mbminlen>1, which includes ucs2, utf16, utf16le, utf32.
The code should be checked for safety against these character sets.
