MaskSpecialCharacters
When set to 1, inverted question marks and acute accents are replaced by apostrophes from almost all string fields when data is transferred to and from the database. This does not occur when set to 0.

This parameter applies to all databases but can be overridden per database.

Valid since DigaSQL 3.22.3523.0; older versions behave as though this parameter were set to 1.
