142 In previous versions FA ignored encoding settings on database/tables, so it depended on server settings,
143 but data stored is encoded in user language encoding. Now we switch to utf8 internal database encoding, while
144 user encoding can be selected independently.
146 To perform safe FA database switch to utf-8 encoding we have to first ensure that all text/char columns
147 have properly set encoding (the same as its content), so the algorithm performed on every table is as follows:
148 . set default table encoding for the table to currently used on client side;
149 . for all text/char column:
150 - suppress autorecoding by change of the type to related binary/blob type
151 - change column to utf8 encodding and selected collation.
152 . change default table encoding to utf8 and selected collation
