In memory db causes '???' to show up instead of data

[Alex-V69]

I tried to use a database in memory and got a table that contains only: '???'

Output from PowerShell

\

Creating a table and inserting first rows:

(none)> .open :memory:
You are now connected to database ":memory:"
:memory:> create table people(sex text);
:memory:> insert into people values('m');
:memory:> insert into people values('f');

After inserting like this for a while:

:memory:> select * from people;
??????????????┼???┼???┼???┼???┼???┼???┼???┼???┼???┼???┼???┼???┼???┼???┼???┼???┼???┼?????
18 rows in set
