What if String properties of TSQLRecord suddenly changed to RawUtf8?

Hello ab,

Lets say I have a TSQLRecord-derived record whose string properties are defined as 'String'.

Now if I changed the source code and all 'String' properties become 'RawUtf8', will error happen when reading back the record data from SQLite db?

Thanks.

No error: it will be transparent.

The data is stored as UTF-8, so with Delphi XE4 did already make the proper conversion from UTF-16 into UTF-8.
So if you change "UnicodeString" into "RawUTF8" properties, you will have the proper UTF-8 encoded data.

Ensure you don't miss any unexpected string/RawUTF8 conversion in your code by following compiler hints.
