Regarding the snippet above: for Unicode-enabled Delphis, using
Clientdataset savetofile as UTF8-based XML (dfXMLUTF8), what do I need
to output for a ftString:
- Field.Size (number of characters in string)
- Field.DataSize (number of bytes in string field)

As Michael indicated, it probably is Field.Size, but I'd like to have
that confirmed. (Can't seem to find any documentation on ClientDataset
XML format on Embarcadero's Delphi help at
http://docwiki.embarcadero.com/VCL/en/DBClient.TCustomClientDataSet.SaveToFile)

Thanks,
Reinier
