SQLite stores texts in either UTF-16 or UTF-8 format depending on how the database is created (sqlite3_open or sqlite3_open16). SQLite will also seamlessly convert between the different formats depending on how you retrieve the texts (sqlite3_column_text or sqlite_column_text16) regardless on what format it has been saved as. There are some cases -like using case insensitive LIKE- where SQLite needs to be extended with the ICU extension to fully work with unicode strings.

Unicode questions seems to come up at least once a week on the mailinglist. Maybe there should be something about this in the FAQ or the features page?

As Igor reminds me, if you create the database file using sqlite3_open16() the default will be UTF-16 instead.

You can work with it in either UTF-8 by using the *_text() APIs, or UTF-16 using the *_text16() calls. It will convert between the two encodings as necessary. The default storage encoding on disk is UTF-8, but it can be changed to UTF-16 with a PRAGMA. Note that I said it "assumes" the data is in that form. SQLite does not validate the encoding, so it is possible to store text data in some other encoding, like SJIS. You will just get strange results when asking SQLite to convert the data, such as when storing it with *_text(), but retrieving it with *_text16(). The sqlite3 shell is intended to work with UTF-8, but because of the way different platforms handle the terminal/console encodings, it can be difficult to use properly. - To unsubscribe, send email to [EMAIL PROTECTED] -
[sqlite] Default Encoding In Sqlite
Whats default encoding in SQLite3 ? How does SQLite3 handles storing Japanese/Chinese text in database? I know in SQL express/sql server I have to use nVarchar/nchar/ntext datatypes to store Japanese/Chinese text in database. It seems that in SQLite3 column having text datatype can also store chinese characters.. Thanks, -Kalyani - To unsubscribe, send email to [EMAIL PROTECTED] -
