Now trying with a newer d/l: <code> SQLite version 3.34.0 2020-12-01 16:14:00 Enter ".help" for usage hints. Connected to a transient in-memory database. Use ".open FILENAME" to reopen on a persistent database. sqlite> select x'c3a1',hex('???'); á|16EC168E16A1 echo "SELECT x'c3a1', hex('á');" | sqlite á|C3A1 </code> The first attempt above would not let me paste the command in. So I had to type 'c3a1' while holding Alt. But rendered as displayed with 3 question marks. Definitely a glitch in my system somewhere.
