The option redgateCompare.oracle.options.ignores.ignoreLengthSemantics = true can be used to ignore differences in the length semantics when diffing databases.

This doesn't count when generating schema-model or migration scripts, as these will always include the length semantic of the source database.

When managing databases with different encodings and different default length semantics, it would be helpful if flyway had an option to omit explicit length semantics when generating those scripts, therefore using the default of the database.
