When I use the flash.data routines to issue a SQLite "PRAGMA encoding" statement, I get an error suggesting that this isn't supported:
'Error #3115: SQL Error.', details:'PRAGMA is not allowed in SQL.', operation:'execute', detailID:'2005
Is there a workaround?
In a word no. See for supported and unsupported features.
However on that page however you will see... System table access is not available The system tables including sqlite_master and other tables with the "sqlite_" prefix are not available in SQL statements. The runtime includes a schema API that provides an object-oriented way to access schema data. For more information see the SQLConnection.loadSchema() method.
For a more detailed help in using loadSchema have a look at,

and consider using,
