Why do you need the whole statement to be Unicode? It looks like the
database wants utf-8. Probably you should encode the data as utf-8 first.

What is coming from wxPython? I guess it is just the data value, not the
SQL statement or the entire script. Try something like
data= u'é' # Unicode data from wxPython
data = data.encode('utf-8')
cur.execute('INSERT INTO tabla VALUES (%s)', [data])
Note I am passing the data as a separate list, not using string
interpolation. Let the database worry about quoting, etc.
