The absence of proper ligatures in Free Serif causes spacing problems. See attached Screen Shot 1 The top line shows the issue in both text and italic styles. It is possible to type in the ligatures fi and fl, but not ff, ffi or ffl. The bottom line shows examples of words with the ligature typed in manually. Is there a setting to automatically substitute proper ligatures for these letter combinations?
I have made a test using other fonts, and the correct ligatures are substituted (Screen Shot 2). This is a possible workaround, but if you type in something like "p dolce", the "p" is no longer the correct symbol for "piano".
