The msfonts package adds fonts that were created by Microsoft; no archlinux package ships them as far as I know. You might want to use these when editing old MS word docs in openoffice.
These fonts are free only for who have a Microsoft Windows license.
Fonts included are: Andale Mono, Arial, Arial Black, Comic, Courier New, Georgia, Impact, Lucida Sans, Lucida Console, Microsoft Sans Serif, Symbol, Tahoma, Times New Roman, Trebuchet, Verdana, Webdings and Wingdings.
To install (manually):
# tar zxvf msfonts-1.2.1.tar.gz # cp -a msfonts-1.2.1/main /usr/X11R6/lib/X11/fonts/ms # cd /usr/X11R6/lib/X11/fonts/ms # ttmkfdir >fonts.scale # mkfontdir # fc-cache -v
