How to print sqlite to file in utf-8?

问题:

I've opened sqlite3.exe in windows console and made a database with special characters. .dump showed me the sql query with special characters. Then I changed output to file: .output file.sql And executed the .dump command.
The special characters were missing when I imported the database using .read file.sql.
I used pragma encoding="UTF-8"; but it didn't change anything (I don't know if it should).

回答1:

The Windows console makes it hard to use UTF-8 correctly, and the Microsoft compiler has lots of bugs that make it impossible to use UTF-8 with portable I/O functions.

If you have entered data in the Windows console, those strings are not valid UTF-8. If a non-ASCII string is output with correct characters in the Windows console, it is not valid UTF-8.

To ensure that your data is valid UTF-8, you have to go through files. Alternatively, use any SQLite shell that does not use the console (such as the SQLite Manager Firefox extension).

This work fine for CP852, but could be used for any codepage known by iconv.

chcp 852 >NUL
echo INSERT into NAMES (name,timestamp) VALUES ('ěščřžýáíé','1429001515'); | iconv.exe -f cp852 -t utf-8 | ..\utilities\sqlite3.exe test.db

Windows can handle unicode internaly, but if you print it on console (by 'echo' command for example) than character mismatch. Using on-the-fly reencoding solve this problem.
