a. Please ensure that quotation marks are paired correctly, e.g. ``good quotes'' rather than ''bad quotes.''
b. Italicized words should not be done in LaTeX's mathmode as this will result in unusual spacing of letters, e.g. compare the difference between features and features (the latter being done in mathmode).
c. Use a hyphen (-) for compound words (e.g. `two-dimensional'), an en-dash (--) to link numbers, nouns or names (e.g. 220--240 Volts, electron--positron collisions, Einstein--Rosen--Podolsky paradox), and an em-dash (---) to link sentences or clauses---this is what we would regard as a `normal' dash.
