I tried it (ALT+NUMPAD keys) and it works OK.

What's surprising is that the second row/value is text, and it's supposed
to be UTF-8 encoded,
yet as far as I know, if not value UTF-8 (0x81 is 129, which should be
encoded on two bytes).

OK, I retried with latest sqlite3.exe, and the results are different:

but still not quite the same, despite the inserted characters being
logically the same (I think).
x'C3BC' is the correct encoding of lower-case umlaut in UTF-8.
x'C281' OTOH is the UTF-8 encoding of char(129), so the code page was not
taken into account (I think), and the byte taken "as-is".
No? --DD

Sorry, slight copy/paste issue on the last message.
there are two rows as expect, but only the second ALT129 entered
Above I made the mistake of using char(220), which is the upper-case U
umlaut.
Below I use char(252) (Unicode code point), and ALT129 (Windows CP437),
which are logically the same letter (lower-case u umlaut), but don't show
up the same.

But you'll notice sqlite3.exe (not the latest, perhaps it matters) doesn't
show the UTF-8 encoded text value correctly,
but does show the table and column name correctly. But does it convert the
Windows CodePage console entered
text to unicode internally, to make the DB portable to another OS? My guess
is that it stores the bytes as-is, which
is why they show up correctly, otherwise why properly convert idents, but
not text values? Pure conjecture though. --DD
PS: Hopefully the above umlaut and ss above, which look correct in Chrome,
will make it across correctly.
[sqlite] How to enter Unicode character?
In case it helps...
In a command-prompt, ALT 156 (hold ALT while pressing 156 on the NUMERIC
keypad) uses the current code-page (British pound sign - ? - for me). ?Using
ALT 0163 (i.e. preceding the character-code with a zero) uses Unicode (also a
?).
I don't have an sqlite3 shell to hand to test with.

Inserting the Unicode character in the table is the next step and it is easy with some SQLite function, but inserting the Unicode character into the table name or the field name, for that matter, is not.

Good day, What OS are you using? Have you read up on this? http://www.fileformat.info/tip/microsoft/enter_unicode.htm Also, Notepad++ is a good text editor for displaying / saving them.

[sqlite] How to enter Unicode character?
Hi, ALL, I live in US and therefore have an English-based laptop with an English-based keyboard. I am also a programmer and would like to test what happen if I have a SQLite table which contains a Unicode character. Now my question is: is it possible to enter a Unicode character (umlaut symbol, german 'ss' character or maybe even something from Chinese alphabet) inside the sqlite3.exe in order to test my program? Thank you.
