Title: Removed "Characters" keyword to match grDevices

The file R/src/library/grDevices/src in the R project has a list of all acceptable keywords. The list does not contain "Characters", which does appear in afm files generated by Rttf3pt1. The result is an ugly warning every time a font is used. This change suppresses the addition of this keyword.
