According to the DBD::SQLite documentation, the connect() syntax is (from the SYNOPSIS):

my $dbh = DBI->connect("dbi:SQLite:dbname=$dbfile","","");

You appear the missing the dbname= part.

I'd suggest you use the utf8 pragma and hard-code the connect() call, with the unicode character(s), directly into your script (or, at least, a test version); e.g.

my $dbh = DBI->connect('dbi:SQLite:dbname=C:\folder-', ...);

Remove all the Tk and SQL code: just attempt to connect to the database. Work on getting that happening. If you encounter difficulties, ask here but include all relevant details (see the "How do I post a question effectively?" guidelines if you're unsure about this step).

Once you have a script that allows you to successfully connect(), start adding the other parts back in a bit at a time.

Repeat the process outlined: fixing small problems as they occur or asking here when you can't. Eventually, you'll have everything fixed — and may still retain much of your original hair :-)
