I don't remember from where I got the numbers. Maybe by reading FB-sources or reading RDB$BYTES_PER_CHARACTER. On my current FB 2.5 installation "64" actually is 1 byte per character, thanks for pointing it out, it allready has been fixed in git master. In MSEgui and the newer ZEOSlib versions the datasize of a string in TDataset record buffer is sizeof(pointer). In MSEgui it is a UnicodeString in ZEOS IIRC a pointer to a special string record.
