I understand that some day (when the official release comes up) "String" 
will be a new String type and thus ANSIString obsolete and just an alias.

So target encoding ID "0" means that " := " will preserve the encoding 
of the source and set the target appropriately without doing a conversion.

Any other encoding ID will be unmodified in the target and a conversion 
will be done if appropriate. (supposedly no conversion when the target's 
encoding ID is "Raw").

Seems clever but not easy stuff to understand. :)
