MAX232E: Capacitor size and rating

Part Number: MAX232E

Two questions:

1. Figure 10 of the MAX232E Data sheet - SLLCS723C - April 2006 - Revised August 2016 shows 1mF next to each capacitor.  Both for the main power as well as the charge pumps.  Yet in section 9.2.2 it states capacitors up to 10uF can be used.  Are the 1mF markings on figure 10 errors, and if so, will they be corrected?

2. What voltage rating is recommended on the charge pump capacitors (C1-C4)?

Thanks,

Peter
