I would guess that your program is handing extended characters to SQLite 
incorrectly.  All strings passed to SQLite are assumed to be Unicode strings.  
This includes not only strings used as parameters when binding to a SQL 
statement, but also the SQL statements themselves.

Given the way you phrased your question, I assume you've been using MBCS.

If you make up a string which depends on a Windows codepage, and do not 
explicitly convert this string to Unicode before handing it to SQLite, you will 
get bad results.  Maybe not immediately, but later, perhaps after indexing.

As a test, please execute this command against both versions of the database:

SELECT path,hex(path) FROM "test-directories" WHERE id=68

You (or we) should be able to tell what's happening from the results of that.

Simon.
