Google inline styles and formatting.
Find the unicode symbol and use that code.
ie try
title2 'Converting Dollars to Euros ^{unicode 0024}1 = ^{unicode 20AC}0.1794';
title3 'Converting Pounds to Yen ^{unicode 00A3}1 = ^{unicode 00A5}144.705';
title4 'You can use copyright ^{unicode 00A9} registered ^{unicode 00AE} and
trademarks ^{unicode 2122} too';
ods text = "^{style [fontsize=18pt] big^{super text}}
or ^{style [fontsize=10pt] small ^{sub text}}";
