Just a quick note regarding Base and using non-English characters in SQL queries. Base defaults to using the font Courier in the custom SQL and log views. This font doesn’t seem to support a very wide range of international glyphs, so text like ‘Αθήνα’ 1 simply doesn’t appear in the text fields!
To fix this problem, open Base preferences to the Logging tab, and pick a different font. In the next release the default font will be Courier New, which has better support for international text.
