QSqlQuery with International chars does not return a result

Question

I have a Sqlite database that has ClipArt tags in, we are translating that database to Swedish however my database query now does not return a result if the characters are non-English British.

For example, fisk == fish and that works perfectly, however öst == east but that fails.

I am constructing the query in a QString from a QLineEdit:

    sqlStatement += QString(" FileID IN (SELECT TLFileID FROM tblTags "
            " INNER JOIN tblTagLinks ON tagId = TLTagId "
            " WHERE tagLanguage LIKE '%1' "
            " AND (tagName LIKE '%2' OR tagName LIKE '%2s' "
            " OR tagLangSWEDISH LIKE '%2' "
            " OR tagLangFINNISH LIKE '%2' "
            " OR tagLangITALIAN LIKE '%2' ))").arg(defaultLanguage, tag);

and then converting it to a QSqlQuery:

qryFiles.prepare(sqlStatement);

if(!qryFiles.exec())

I know the database has the chars because I have been importing and exporting the data to CSV for the translators to translate, using a Sqlite admin tool and Excel.

Do I have to open the database in a special way?

I am using Qt 4.5.2, Windows XP, VS2008, Sqlite 3.5.1

Answer 1

I know it might be obvious, but did you check what character sets your db and your application use? I would guess that you're using native Windows coding in one and UTF8 in the other.

Sorry for the obvious answer, but that's the cause of most of my internationalization problems.
